Question

verify a - (-b) = a+ b for the following values of a and b.i) a = -17 b= + 15 ii) a = 50 b= 21​

Answer 1

Answer:

a-(-b) = a+b

(1) a = (-17) b = 15

= -17 - (-15) = -17 + 15

= -17 + 15 = 17 - 15

= 17 - 15 = 2

= 2 = 2

Hence verified!

(2) a = 50 b = 21

= 50 - (-21) = 50 + 21

= 50 + 21 = 71

= 71 = 71

Hence verified!
