Question

verify a-(-b) =a+b for the following values of a and b. 1)a=-17. 2)b=+15. 3) a=50. 4) b=21.​

Answer 1

Answer:

(a)

Given that

a=-17, B=15

to verify a-(-b)=a+b

=-27-(-15)=-17+15

=-27+15=-2

=-2=-2

Hence verified a-(-b) =a+b

(b)

given that a=50,b=21

To verify a-(-b) =a+b

=50-(-21)=50+21

=50+21=71

=71=71

hence verified a-(-b) =a+b
