Verify a – (-b) = a + b for the following values of a and b. i) a = -17 b = +15

$\red{\mid{\fbox{\tt{Solution: }}\mid}} \:$

Need to verify :

$\displaystyle{↪ \: a - ( - b) = a + b}$

★ According to the given question :

$→ \: - 17 - ( - 15) = - 17 + 15$

$→ \: - 17 + 15 = - 17 + 15$

$→ \: - 2 = - 2$

$\sf\blue{Hence, Verified } \:$
