Question

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

(ii) a = 118, b = 125​

Answer 1

From the question,

a = 118 and b = 125

To verify a – (- b) = a + b

Let us take Left Hand Side (LHS) = a – (- b)

= 118 – (- 125)

= 118 + 125

= 243

Now, Right Hand Side (RHS) = a + b

= 118 + 125

= 243

By comparing LHS and RHS

LHS = RHS

243 = 243

Hence, the value of a and b is verified.

Answer 2

ii)

.118-(-125)=118+125=243

a+b=118-125=243.
