Which two signs should be interchanged in the following equation to make it correct?
28 - 42 ÷ 2 + 276 × 23 = - 44
Show answer & explanation
Correct answer: C
Explanation
Correct Answer is option 3 i.e. × and ÷
Given equation: 28 - 42 ÷ 2 + 276 × 23 = - 44
From option 3, by interchanging signs × and ÷, we get
28 - 42 × 2 + (276 ÷ 23) = - 44
28 - (42 × 2) + 12 = - 44
(28 + 12) - 84 = - 44
40 - 84 = - 44
- 44 = - 44
Hence, the correct answer is × and ÷.
