Question

Verify a – (– b) = a + b for the following values of a and b.
(i) a = 25, b = 12
(ii) a = 113 b = 16
NCERT Class 7th Mathematics Chapter 1 Integers

Answer 1

Answer:

Step-by-step explanation:

(i) a = 25, b = 12

L.H.S = a – (– b)

         = 25 - ( - 12 )

         = 25 + 12

         = 37

R.H.S = a + b

          = 25 + 12

          = 37

L.H.S = R.H.S

(ii) a = 113       b = 16

L.H.S = a – (– b)

         = 113 - ( - 16 )

         = 113 + 16

          = 129

R.H.S = a + b

          = 113 + 16

          = 129

L.H.S = R.H.S

Hence verified.
