Question

Verify a-(-b) =a+b for the following values of a and b

Answer 1

Let's take the value for A as 1 and for B as 2 so,
Put the values in
LHS 1-(-2) = 1+2 = 3
RHS 1+2 = 3

Answer 2

Step-by-step explanation:

Let us take a=21 b=18

a – (-b)  = 21-(-18)

21-(-18) = 21 + 18

21+18= 39

a + b = 21+18

21+18 = 39

21-(-18) = 21+18 = 39
