Question

what is the sum of number and it's additive inverse ?​

Answer 1

Anwer is 0 and here is explanation.

Let a be any number and b be also any number

Now,

a/b + (-a/b) (where -a/b is additive

inverse of a/b)

So, LCM of denominators of both number is b.

a+(-a)/b

= a-a/b

=0/b

=0

Hence, sum of number with their additive inverse is 0.
