Question

Choose the correct answer from the given four options.

For any two integers $a$ and $b$, which of the following suggests that the operation of addition is commutative?

• A. $a\times b=b\times a$
• B. $a+b=b+a$
• C. $a-b=b-a$
• D. $a+b>a$

Answer 1

The correct option is B

$a+b=b+a$

Commutative property of addition is defined as Changing the order of addends does not change the sum.

So, in each option

(A) $a\times b=b\times a$ it is the Commutative property of multiplication.

(B) $a+b=b+a$ it is the Commutative property of addition.

(C) $a-b=b-a$ in case of subtraction commutative property does not follow.

(D)$a+b>a$it is not the commutative property because it does not contain equal sign between both the sides of expressions.

Hence, the correct answer is $a+b=b+a$
