Integers are not closed under addition.

Example:

A) i) Take 2 integers (-2) and 3.

ii) Add them.

=(-2)+3

=-2+3

=1

So, the sum is also an integer.

B) ii) Take another 2 integers 6 and 8.

ii) Add them.

=6+8

=14

So, in this case also the sum is an integer.

HENCE IT IS PROVED THAT INTEGERS ARE NOT CLOSED UNDER ADDITION.
