Question

Simplify each of the following:

$63-(-3)\left\{-2-\overline{8-3}\right\}÷3\{5+(-2\left)\right(-1\left)\right\}$

Answer 1

On applying the BODMAS rule, we get:

63 $-$ ($-$ 3) {$-$ 2 $-$ $\overline{8-3}$} ÷ 3 {5 + ($-$ 2) ($-$1)}
= 63 $-$ ($-$ 3) {$-$ 2 $-$ 5} ÷ 3 {5 + 2} (On simplifying vinculum)
= 63 $-$ ($-$ 3) ($-$ 7 ) ÷ 3 × 7 (On simplifying braces)
= 63 $-$ ($21÷21$)
= 63 $-$ 1
= 62
