Answer 1

Hey mate!

Here's your answer...

ANSWER:-

Commutative Property of Addition.

REASON:-

According to this property, when we add two integers, the answer will remain unchanged even if the position of the numbers are changed. Let A and B are two integers, then;

Hence,

A + B = B + A

EXAMPLES:-

1 + 2 = 2 + 1 = 3

3 + 8 = 8 + 3 = 11

12 + 5 = 5 + 12 = 17.
