Which two signs should be interchanged to make the equation mathematically correct?
8 + 32 ÷ 16 × 11 − 5 = 22
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. + and ×
Given equation: 8 + 32 ÷ 16 × 11 − 5 = 22
Option 1: + and ×
After interchanging the expression becomes:
= 8 × 32 ÷ 16 + 11 − 5 = 22
= 8 × 2 + 11 − 5
= 16 + 11 − 5
= 22 = 22
As we have found our answer, there is no need to check further options.
Hence, + and × is the correct answer.
