Question

Evaluate:$88-[5-(-48)÷(-16\left)\right]$.

Answer 1

To evaluate an expression , we must first simplify the expression below the vinculum, then inside the small bracket , then inside the curly bracket , and finally inside the square bracket using the DMAS rule,
Also, the division of an integer by an integer of the same signs is always positive.

Thus, $88-[5-(-48)÷(-16\left)\right]$
$=88-[5-3]$
[Division of negative integers : $\left(48\right)÷(-16)=3]$

$=88-2$
[Removing curly bracket]
$=86$

$\therefore$ The value of $88-[5-(-48)÷(-16\left)\right]$ is $86$.
