Question

if a=12,b=4, find whether a+b=b+a​

Answer 1

Answer:

The closure property states that if a and b are two different integers, then their sum also must be an integer. Then the number is said to be closed.

a + b

= -12 + 4

= -8

Which is an integer.

So both these numbers are closed under addition.
