The commutative property of addition states that changing the order of the addends does not change the sum.

A. 7+8=8+7

This shows that swapping the numbers being added does not change the sum.

7+8=15, so both sides are equal.

This is a clear example of the commutative property of addition.

B. 7x(2+3)=14+21.

This equation involves both addition and multiplication, and it seems to be applying the distributive pr...
