Question

For a = -12, b = 4, C = -25, find whether
(a) a and b are closed under addition.​

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.
