Commutative, Associative and Distributive Laws

Commutative, Associative and Distributive Laws

Wow! What a mouthful of words! But the ideas are simple.

Commutative Laws

The "Commutative Laws" say we can swap numbers over and still get the same answer ...
... when we add:
a + b  =  b + a

Example:

Commutative Law Addition

... or when we multiply:
a × b  =  b × a

Example:

Commutative Law multiplication

Commutative Percentages!

Because a × b  =  b × a it is also true that a% of b  =  b% of a

Example: 8% of 50 = 50% of 8, which is 4


commute
Why "commutative" ... ?
Because the numbers can travel back and forth like a commuter.


Associative Laws

The "Associative Laws" say that it doesn't matter how we group the numbers (i.e. which we calculate first) ...
... when we add:
(a + b) + c  =  a + (b + c)
Associative Law addition
... or when we multiply:
(a × b) × c  =  a × (b × c)

Associative Law multiplication

Examples:

This:(2 + 4) + 5  =  6 + 5  =  11
Has the same answer as this:2 + (4 + 5)  =  2 + 9  =  11

This:(3 × 4) × 5  =  12 × 5  =  60
Has the same answer as this:3 × (4 × 5)  =  3 × 20  =  60

Uses:

Sometimes it is easier to add or multiply in a different order:

What is 19 + 36 + 4?

19 + 36 + 4  =  19 + (36 + 4) 
=  19 + 40 = 59
Or to rearrange a little:

What is 2 × 16 × 5?

2 × 16 × 5  =  (2 × 5) × 16 
=  10
 × 16 = 160

Distributive Law

The "Distributive Law" is the BEST one of all, but needs careful attention.
This is what it lets us do:
Distributive Law
3 lots of (2+4) is the same as 3 lots of 2 plus 3 lots of 4
So, the  can be "distributed" across the 2+4, into 3×2 and 3×4
And we write it like this:
a × (b + c)  =  a × b  +  a × c
Try the calculations yourself:
  • 3 × (2 + 4)  =  3 × 6  =  18
  • 3×2 + 3×4  =  6 + 12  =  18
Either way gets the same answer.
In English we can say:
We get the same answer when we:
  • multiply a number by a group of numbers added together, or
  • do each multiply separately then add them

Uses:

Sometimes it is easier to break up a difficult multiplication:

Example: What is 6 × 204 ?

6 × 204  =  6×200 + 6×4
=  1,200 + 24
=  1,224
Or to combine:

Example: What is 16 × 6 + 16 × 4?

16 × 6 + 16 × 4  =  16 × (6+4)
= 16 × 10
=  160
We can use it in subtraction too:

Example: 26×3 - 24×3

26×3 - 24×3 = (26 - 24) × 3
=  2 × 3
=  6
We could use it for a long list of additions, too:

Example: 6×7 + 2×7 + 3×7 + 5×7 + 4×7

6×7 + 2×7 + 3×7 + 5×7 + 4×7
(6+2+3+5+4) × 7
20 × 7
140

And those are the Laws . . .

                  . . . but don't go too far!

The Commutative Law does not work for subtraction or division:

Example:

  • 12 / 3 = 4, but
  • 3 / 12 = ¼
 The Associative Law does not work for subtraction or division:

Example:

  • (9 – 4) – 3 = 5 – 3 = 2, but
  • 9 – (4 – 3) = 9 – 1 = 8
 The Distributive Law does not work for division:

Example:

  • 24 / (4 + 8) = 24 / 12 = 2, but
  • 24 / 4 + 24 / 8 = 6 + 3 = 9

Summary

Commutative Laws:a + b  =  b + a
a × b  =  b × a
Associative Laws:(a + b) + c  =  a + (b + c)
(a × b) × c  =  a × (b × c)
Distributive Law:a × (b + c)  =  a × b  +  a × c

China , US, Australia , Japan and India rising tension and a protracted cold war

Bulletin TheAustralian reported...
Escalating hostilities between China and the US are reaching a point of no return. US Secretary of State Mike Pompeo has delivered his most damning indictment of the Chinese Communist Party to date. Rumination about war developing between the two nations has been superseded by concern over whether the US is prepared to defend itself as well as allied states should relations deteriorate.
The Australian government is no longer sitting on the fence. It has taken the moral high ground by siding with the leader of the free world. However, without sufficient military preparation or a geopolitical strategy that establishes new alliances and trade diversification, our capacity to survive a protracted cold war with China is limited.
Under Xi Jinping, China has become a menace to the international community.
TheGuardian

Australia to step up South China Sea defence cooperation with US – but won't commit to patrols

Allies release joint statement of ‘deep concern’ over China’s actions in Hong Kong and repression of Uighurs and vow to fight disinformation
Australia has pledged to increase defence cooperation with the US in the South China Sea – but stopped short of making any specific new commitment on freedom of navigation operations, despite American pressure.
The two allies have also decided during high-level talks in Washington to set up a working group to push back at false information across the Indo-Pacific region, warning that “state-sponsored malicious disinformation and interference in democratic processes are significant and evolving threats”.
While the joint statement expressed “deep concern” over a range of actions taken by China – including a “campaign of repression of Uyghurs” and undermining of freedoms in Hong Kong – Australia’s foreign affairs minister, Marise Payne, said her country had “no intention of injuring” its important relationship with Beijing.
Payne and the defence minister, Linda Reynolds, agreed in face-to-face talks with their US counterparts, Mike Pompeo and Mark Esper, to pursue “increased and regularised maritime cooperation” in the South China Sea and the Indian Ocean, “bilaterally and in concert with other likeminded and regional partners”.
The joint statement declares that Beijing’s maritime claims in the South China Sea “are not valid under international law”, but Australia appears to have held firm against conducting freedom of navigation exercises within 12 nautical miles of disputed features.
Experts say the US has long been pushing for Australia to conduct such exercises, but Australia has resisted taking such a step to date – in part to avoid inflaming tensions with China, its largest trading partner.
Payne said Australia and the US had a close and enduring relationship but made their own decisions based on their values.

Triangular Number Sequence

Triangular Number Sequence

This is the Triangular Number Sequence:
1, 3, 6, 10, 15, 21, 28, 36, 45, ...
It is simply the number of dots in each triangular pattern:
triangular numbers
By adding another row of dots and counting all the dots we can
find the next number of the sequence.
  • The first triangle has just one dot.
  • The second triangle has another row with 2 extra dots, making 1 + 2 = 3
  • The third triangle has another row with 3 extra dots, making 1 + 2 + 3 = 6
  • The fourth has 1 + 2 + 3 + 4 = 10
  • etc!
How may dots in the 60th triangle?

A Rule

We can make a "Rule" so we can calculate any triangular number.
First, rearrange the dots like this:
triangular numbers 1 to 5
Then double the number of dots, and form them into a rectangle:
triangular numbers when doubled become n by n+1 rectangles
Now it is easy to work out how many dots: just multiply n by n+1
Dots in rectangle = n(n+1)
But remember we doubled the number of dots, so
Dots in triangle = n(n+1)/2
We can use xn to mean "dots in triangle n", so we get the rule:
Rule: xn = n(n+1)/2
Example: the 5th Triangular Number is
x5 = 5(5+1)/2 = 15
Example: the 60th is
x60 = 60(60+1)/2 = 1830
Wasn't it much easier to use the formula than to add up all those dots?
log stack

Example: You are stacking logs.

There is enough ground for you to lay 22 logs side-by-side.
How many logs can you fit in the stack?
x22 = 22(22+1)/2 = 253

The stack may be dangerously high, but you can fit 253 logs in it!

Perfect Numbers

Perfect numbers

Any positive integer that is equal to the sum of its distinct proper factors (factors other than the number itself).
Example: 6 (proper factors: 1,2,3) is a Perfect number because 1+2+3=6.
Example: 28 (proper factors: 1,2,4,7,14) is also a Perfect number, because 1+2+4+7+14=28.
Euclid proved that 2n-1(2n-1) is an even perfect number when 2n-1 is a Mersenne prime. These are now called Euclid numbers and Euler proved that all even Perfect numbers are of this form for some positive prime number n. Thus, 6, 28, 496 are Perfect and correspond to values of 3, 7, and 31 for 2n-1 in the formula.
This table shows the results for n=1 to 13 which include the first five Perfect numbers:
n2n-12n-1(2n-1)Perfect?Comment
111Non is not prime
236Yesn is prime, 2n-1 is prime
3728Yesn is prime, 2n-1 is prime
415120Non is not prime
531496Yesn is prime, 2n-1 is prime
6632016Non is not prime
71278128Yesn is prime, 2n-1 is prime
8 to 10......Nonot prime
1120472096128Non is prime, but 2n-1 is not prime
1240958386560Non is not prime
13819133550336Yesn is prime, 2n-1 is prime
Whether there are infinitely many even Perfect numbers or any odd perfect numbers remain unsolved questions.

A China Silk Road -A train from China to Europe. History unreveal

The first direct rail freight service from China to the UK has completed its 18-day trip and arrived in London.

The train left the city of Yiwu, on China's east coast, this month and travelled 7,500 miles (12,000km), crossing seven countries, before arriving at a freight depot in Barking.

The service delivered 34 containers of clothes and high street goods.

China Railway already runs services between China and other European cities, including Madrid and Hamburg.

The service passed through Kazakhstan, Russia, Belarus, Poland, Germany, Belgium and France before entering the UK via the Channel Tunnel.



Map showing route of the train

In order to make the journey, a number of different locomotives and wagons were used as the railways of the former Soviet Union states have a larger rail gauge.

However, the rail firms say the service is still cheaper than air freight and faster than sending goods by sea.

The service is part of China's One Belt, One Road programme - reviving the ancient Silk Road trading routes to the West.

The Silk Road was an ancient network of trade routes, formally established during the Han Dynasty of China, which linked the regions of the ancient world in commerce between 130 BCE-1453 CE. As the Silk Road was not a single thoroughfare from east to west, the term 'Silk Routes’ has become increasingly favored by historians, though 'Silk Road’ is the more common and recognized name.

The European explorer Marco Polo (1254-1324 CE) traveled on these routes and described them in depth in his famous work but he is not credited with naming them. Both terms for this network of roads were coined by the German geographer and traveler, Ferdinand von Richthofen, in 1877 CE, who designated them 'Seidenstrasse’ (silk road) or 'Seidenstrassen’ (silk routes). Polo, and later von Richthofen, make mention of the goods which were transported back and forth on the Silk Road. 


Goods Traded via the silk road

While many different kinds of merchandise traveled along the Silk Road, the name comes from the popularity of Chinese silk with the west, especially with Rome. The Silk Road routes stretched from China through India, Asia Minor, up throughout Mesopotamia, to Egypt, the African continent, Greece, Rome, and Britain.

The northern Mesopotamian region (present-day Iran) became China’s closest partner in trade, as part of the Parthian Empire, initiating important cultural exchanges.  Paper, which had been invented by the Chinese during the Han Dynasty, and gunpowder, also a Chinese invention, had a much greater impact on culture than did silk. The rich spices of the east, also, contributed more than the fashion which grew up from the silk industry. Even so, by the time of the Roman Emperor Augustus (r.27 BCE – 14 CE) trade between China and the west was firmly established and silk was the most sought-after commodity in Egypt, Greece, and, especially, in Rome.

the Roman love of silk

Prior to becoming Emperor Augustus, Octavian Caesar seized on the controversial topic of silk clothing to denounce his adversaries Mark Antony (83-30 BCE) and Cleopatra VII (69-30 BCE) as immoral. As they both favored Chinese silk, which was increasingly becoming associated with licentiousness, Octavian exploited the link to deprecate his enemies. Octavian would triumph over Antony and Cleopatra; he could do nothing, however, to curtail the popularity of silk.

Important facts about Trapezoid or Trapezium

A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel (marked with arrows below):

trapezoid Isosceles trapezoid
Trapezoid Isosceles Trapezoid

A trapezoid:

right arrowhas a pair of parallel sides
right arrow

is an isosceles trapezoid when it has equal angles from a parallel side

right arrowis called a "trapezium" in the UK (see below)

 

trapezoid base leg and altitude

The parallel sides are the "bases"

The other two sides are the "legs"

The distance (at right angles) from one base to the other is called the "altitude"

Area of a Trapezoid

trapezoid a, b, h 

The Area is the average of the two base lengths times the altitude:

Area = a+b2 × h

Example: A trapezoid's two bases are 6 m and 4m, and it is 3m high. What is its Area?

Area  =  6 m + 4 m2 × 3 m  =  5 m × 3 m  =  15 m2

The Area of Polygon by Drawing tool is helpful when you can draw your Trapezoid.

Perimeter of a Trapezoid

The Perimeter is the distance around the edges.

trapezoid perimeter a+b+c+d 

The Perimeter is the sum of all side lengths:

Perimeter = a+b+c+d

Example: A trapezoid has side lengths of 5 cm, 12 cm, 4 cm and 15 cm, what is its Perimeter?

Perimeter = 5 cm + 12 cm + 4 cm + 15 cm = 36 cm

Median of a Trapezoid

trapezoid median half-way between a and b 

The median (also called a midline or midsegment) is a line segment half-way between the two bases.

The median's length is the average of the two base lengths:

m = a+b2

You can calculate the area when you know the median, it is just the median times the height:

Area = mh

Trapezium

trapezium (UK: trapezoid) is a quadrilateral with NO parallel sides.

The US and UK have their definitions swapped over, like this:

 TrapezoidTrapezium
US:a pair of parallel sidesNO parallel sides
UK:NO parallel sidesa pair of parallel sides

16 Superfoods That Are Above-and-Beyond Healthy

1. Dark Leafy Greens

Dark green leafy vegetables (DGLVs) are an excellent source of nutrients including folate, zinc, calcium, iron, magnesium, vitamin C and fiber.

Part of what makes DGLVs so super is their potential to reduce your risk of chronic illnesses including heart disease and type 2 diabetes (12).

They also contain high levels of anti-inflammatory compounds known as carotenoids, which may protect against certain types of cancer (3).

Some well-known DGLVs include:

  • Kale
  • Swiss chard
  • Collard greens
  • Turnip greens
  • Spinach
Some DGLVs have a bitter taste and not everyone enjoys them plain. You can get creative by including them in your favorite soups, salads, smoothies, stir-fries and curries.
Summary
Dark green leafy vegetables are full of fiber and nutrients which may be instrumental in preventing certain chronic diseases.

2. Berries

Berries are a nutritional powerhouse of vitamins, minerals, fiber and antioxidants.

The strong antioxidant capacity of berries is associated with a reduced risk of heart disease, cancer and other inflammatory conditions (45).

Berries may also be effective in treating various digestive and immune-related disorders when used alongside traditional medical therapies (6).

Some of the most common berries include:

  • Raspberries
  • Strawberries
  • Blueberries
  • Blackberries
  • Cranberries
Whether you enjoy them as part of your breakfast, as a dessert, on a salad or in a smoothie, the health benefits of berries are as versatile as their culinary applications.

Summary
Berries are full of nutrients and antioxidants which may prevent certain diseases and improve digestion.


3. Green Tea

Originally from China, green tea is a lightly caffeinated beverage with a wide array of medicinal properties.

Green tea is rich in antioxidants and polyphenolic compounds which have strong anti-inflammatory effects. One of the most prevalent antioxidants in green tea is the catechin epigallocatechin gallate, or EGCG.

EGCG is likely what gives green tea its apparent ability to protect against chronic diseases including heart disease, diabetes and cancer (78).

Research also indicates that the combination of catechins and caffeine in green tea may make it an effective tool for weight loss in some people (9).

Summary

Green tea is antioxidant-rich with many health benefits including possible cancer prevention.


4. Eggs

Eggs have historically been a controversial topic in the nutrition world due to their high cholesterol content, but they remain one of the healthiest foods.

Whole eggs are rich in many nutrients including B vitamins, choline, selenium, vitamin A, iron and phosphorus.

They’re also loaded with high-quality protein.

Eggs contain two potent antioxidants, zeaxanthin and lutein, which are known to protect vision and eye health (1011).

Despite fears surrounding egg consumption and high cholesterol, research indicates no measurable increase in heart disease or diabetes risk from eating up to 6–12 eggs per week (12).

In fact, eating eggs could increase “good” HDL cholesterol in some people, which may lead to a favorable reduction in heart disease risk. More research is needed to draw a definite conclusion (13).

Summary

Eggs are rich in high-quality protein and unique antioxidants. Research indicates that eating eggs regularly will not increase your risk of heart disease or diabetes.

5. Legumes

Legumes, or pulses, are a class of plant foods made up of beans (including soy), lentils, peas, peanuts and alfalfa.

They earn the superfood label because they’re loaded with nutrients and play a role in preventing and managing various diseases.

Legumes are a rich source of B vitamins, various minerals, protein and fiber.

Research indicates that they offer many health benefits including improved type 2 diabetes management, as well as reduced blood pressure and cholesterol (14).

Eating beans and legumes regularly may also promote healthy weight maintenance, due to their ability to improve feelings of fullness (15).

Summary

Legumes are rich in many vitamins, protein and fiber. They may prevent some chronic diseases and support weight loss.


6. Nuts and Seeds


Nuts and seeds are rich in fiber, vegetarian protein and heart-healthy fats.

They also pack various plant compounds with anti-inflammatory and antioxidant properties, which can protect against oxidative stress (16).

Research indicates that eating nuts and seeds can have a protective effect against heart disease (17).

Common nuts and seeds include:

  • Almonds, pecans, pistachios, walnuts, cashews, Brazil nuts, macadamia nuts.
  • Peanuts — technically a legume, but often considered a nut.
  • Sunflower seeds, pumpkin seeds, chia seeds, flaxseeds, hemp seeds.

Interestingly, even though nuts and seeds are calorically dense, some types of nuts are linked to weight loss when included in a balanced diet (181920).

Summary

Nuts and seeds are full of fiber and heart-healthy fats. They may reduce your risk of heart disease and support weight loss.


7. Kefir (And Yogurt)

Kefir is a fermented beverage usually made from milk that contains protein, calcium, B vitamins, potassium and probiotics.

Kefir is similar to yogurt but has a thinner consistency and typically more probiotic strains than yogurt.

Fermented, probiotic-rich foods like kefir have several associated health benefits, including reduced cholesterol, lowered blood pressure, improved digestion and anti-inflammatory effects (212223).

Though kefir is traditionally made from cow’s milk, it’s typically well tolerated by people with lactose intolerance due to the fermentation of the lactose by bacteria.

However, it’s also made from non-dairy beverages such as coconut milk, rice milk and coconut water.

Summary

Kefir is a fermented dairy beverage with multiple health benefits related to its probiotic content. Though generally made from cow’s milk, kefir is also available in non-dairy forms.

You can purchase kefir or make it yourself. If you’re choosing a commercially prepared product, be mindful of added sugar.

8. Garlic

Garlic is a plant food that is closely related to onions, leeks and shallots. It’s a good source of manganese, vitamin C, vitamin B6, selenium and fiber.

Garlic is a popular culinary ingredient due to its distinct flavor, but it has also been used for its medicinal benefits for centuries.

Research indicates that garlic may be effective in reducing cholesterol and blood pressure, as well as supporting immune function (24).

What’s more, sulfur-containing compounds in garlic may even play a role in preventing certain types of cancer (25).

Summary

Garlic is a nutrient-rich food used for its medicinal benefits for centuries. It may be useful for supporting immune function and reducing your risk of heart disease and certain cancers.


9. Olive Oil

Olive oil is a natural oil extracted from the fruit of olive trees and one of the mainstays of the Mediterranean diet.

It’s biggest claims to health are its high levels of monounsaturated fatty acids (MUFAs) and polyphenolic compounds.

Adding olive oil to your diet may reduce inflammation and your risk of certain illnesses such as heart disease and diabetes (262728).


Summary

Olive oil is one of the principle fat sources in the Mediterranean diet. It may be beneficial in reducing heart disease, diabetes and other inflammatory conditions

It also contains antioxidants such as vitamins E and K, which can protect against cellular damage from oxidative stress.

10. Ginger

Ginger comes from the root of a flowering plant from China. It’s used as both a culinary flavor enhancer and for its multiple medicinal effects.

Ginger root contains antioxidants, such as gingerol, that may be responsible for many of the reported health benefits associated with this food.

Ginger may be effective for managing nausea and reducing pain from acute and chronic inflammatory conditions (293031).

It may also reduce your risk of chronic illnesses such as heart disease, dementia and certain cancers (323334).

Summary

Ginger is available fresh, as an oil or juice and in dried/powdered forms. It’s easy to incorporate into soups, stir-fries, sauces and teas.

Ginger is used for its flavor and potential medicinal effects. It may be useful in treating nausea, pain and preventing certain chronic diseases.

11. Turmeric (Curcumin)

Turmeric is a bright yellow spice that is closely related to ginger. Originally from India, it’s used for cooking and its medicinal benefits.

Curcumin is the active compound in turmeric. It has potent antioxidant and anti-inflammatory effects and is the focus of most research surrounding turmeric.

Studies show that curcumin may be effective in treating and preventing chronic diseases such as cancer, heart disease and diabetes (3536).

It may also aid wound healing and pain reduction (3738).

One drawback of using curcumin medicinally is that it’s not easily absorbed by your body, but its absorption can be enhanced by pairing it with fats or other spices such as black pepper.

Summary

The active compound in turmeric, curcumin, is associated with several medicinal effects. Curcumin is not easily absorbed and should be paired with substances that enhance its absorption, such as black pepper.

12. Salmon

Salmon is a highly nutritious fish packed with healthy fats, protein, B vitamins, potassium and selenium.

It’s one of the best sources of omega-3 fatty acids, which are known for a variety of health benefits, such as reducing inflammation (39).

Including salmon in your diet may also lower your risk of heart disease and diabetes and help you maintain a healthy weight (40).

A potential drawback of eating salmon and other types of seafood is their possible contamination with heavy metals and other environmental pollutants.

You can avoid potential negative effects by limiting your consumption of fish to two to three servings per week (41).

Summary

Salmon is a good source of many nutrients, especially omega-3 fatty acids. Limit your consumption of salmon to avoid potential negative effects from contaminants common in fish and seafood.


13. Avocado

Avocado is a highly nutritious fruit, though it’s often treated more like a vegetable in culinary applications.

It’s rich in many nutrients, including fiber, vitamins, minerals and healthy fats (42).

Similar to olive oil, avocado is high in monounsaturated fats (MUFAs). Oleic acid is the most predominant MUFA in avocado, which is linked to reduced inflammation in the body (43).

Eating avocado may reduce your risk of heart disease, diabetes, metabolic syndrome and certain types of cancer (444546).


Summary

Avocados are nutrient-rich, high-fiber fruits that may play a role in reducing inflammation and chronic diseases.


14. Sweet Potato

The sweet potato is a root vegetable loaded with many nutrients, including potassium, fiber and vitamins A and C.

They’re also a good source of carotenoids, a type of antioxidant that may reduce your risk of certain types of cancer (47).

Despite their sweet flavor, sweet potatoes don’t increase blood sugar as much as you might expect. Interestingly, they may actually improve blood sugar control in those with type 2 diabetes (48).


Summary

Sweet potatoes are a highly nutritious food loaded with carotenoids, which have strong antioxidant properties. They may also be beneficial for blood sugar control.


15. Mushrooms

Some of the most common varieties of edible mushrooms are button, portobello, shiitake, crimini and oyster mushrooms.

Though nutrient content varies depending on the type, mushrooms contain vitamin A, potassium, fiber, and several antioxidants not present in most other foods (49).

Interestingly, eating more mushrooms is associated with greater consumption of vegetables in general, contributing to an overall more nutritious diet (50).

Due to their unique antioxidant content, mushrooms may also play a role in reducing inflammation and preventing certain types of cancers (495051).

Another super feature of mushrooms is that agricultural waste products are used to grow them. This makes mushrooms a sustainable component of a healthy food system (50).

Summary

Mushrooms are full of nutrients and may reduce your risk of certain diseases. Additionally, mushrooms are a sustainable food choice.


16. Seaweed

Seaweed is a term used to describe certain nutrient-rich sea vegetables. It’s most commonly consumed in Asian cuisine but is gaining popularity in other parts of the world due to its nutritional value.

Seaweed packs multiple nutrients, including vitamin K, folate, iodine and fiber.

These ocean vegetables are a source of unique bioactive compounds — not typically present in land-vegetables — which may have antioxidant effects.

Some of these compounds may also reduce your risk of cancer, heart disease, obesity and diabetes (52).

Summary

Seaweed is a group of highly nutritious sea vegetables that may play a role in protecting against certain chronic diseases.
