Properties of Numbers: Commutative Property of Addition

The video tutorial explains the concept of commuters and introduces the term 'commutative,' derived from 'commute,' meaning to move around. It then delves into the commutative property of addition, illustrating with apples how the order of numbers being added does not affect the sum. The tutorial further demonstrates this property with different numerical expressions, emphasizing that reordering numbers results in the same total.

What is the origin of the word 'commutative'?

• It is derived from the word 'compute'.

• It is derived from the word 'commute'.

• It is derived from the word 'community'.

• It is derived from the word 'communication'.

In the example with apples, what does the commutative property demonstrate?

• The sum is always smaller when smaller numbers are added first.

• The sum is always greater when larger numbers are added first.

• The sum remains the same regardless of the order of numbers.

• The sum changes when the order of numbers is reversed.

How many apples are there in total when 3 apples are added to 5 apples?

• 10 apples

• 8 apples

• 9 apples

• 7 apples

What does the commutative property of addition state?

• The order of numbers affects the sum.

• The sum is always zero.

• The sum is always negative.

• The order of numbers does not affect the sum.

In the expression 6 + 7 + 3 + 5, what is the total sum?

• 21

• 20

• 19

• 18
