Answer 2

$\sf\underline{\underline{\bigstar\:Question:}}$

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

(i) a = 21, b = 18.

$\sf\underline{\underline{\bigstar\:Solution:}}$

$\rm\bold{Let \: us \: verify \: by \: putting \: the \: values,}$

$\:\:\:\:\:::\implies{21 - ( - 18) = 21 + 18}$

$\: \: \: \: \: \: \: \: : :\implies 39 = 39$

$\rm\bold{Hence,Verified.}$
