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)]
=88−[5−3]
[Division of negative integers : (48)÷(−16)=3]
=88−2
[Removing curly bracket]
=86
∴ The value of 88−[5−(−48)÷(−16)] is 86.
