Question

verify a_(_b)=a+b;a=21;b=18​

Answer 1

Answer:

Given, a = 21 and b = 18

so,

$a - ( - b) = a + b \\ \\ = > 21 - ( - 18) = 21 + 18 \\ \\ = > 21 + 18 = 21 + 18 \\ \\ = > 39 = 39$

LHS = RHS ✅

hope it helps uH

Answer 2

a−(−b)=a+b

or, 21−(−18)=21+18

or, 21+18=21+18

or, 39=39

LHS = RHS . Verified.
