Select the correct combination of mathematical signs to sequentially replace the * signs and balance the given equation.
45 * 86 * 23 * 36 * 18 * 2021
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. +, ×, −, ÷, =.
Given equation: 45 * 86 * 23 * 36 * 18 * 2021
Option 1: +, ×, −, ÷, =
After interchanging the expression becomes:
= 45 + 86 × 23 − 36 ÷ 18 = 2021
= 45 + 86 × 23 − 2
= 45 + 1978 − 2
= 2023 - 2
= 2021 = 2021
Hence, +, ×, −, ÷, = is the correct answer.
