Answer 1

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

ii) a = 50b=21​

a+b=a+b

50+21=50+21

71=71

Step-by-step explanation:

Answer 2

Answer:

we know that : a - (-b) = a + b

                       minus and plus is minus

                       and minus and minus or plus plus is always plus

suppose: a =50; b=21  

              =50 - (-21)

              =50 + 21  

              =71

hence, proved a -(-b)=a +b
