The following equation becomes mathematically correct when you interchange either the sign or the numbers as indicated in the question. Find the correct alternative. Given equation:(16 - 4) x 6 ÷ 2 + 8 = 30
Correct answer: B. ÷ and -
- A. 4 and 2
- B. ÷ and -
- C. 16 and 6
- D. - and +
Explanation
By interchanging the '÷' and '-' signs, the equation becomes (16 ÷ 4) × 6 - 2 + 8. This simplifies to 4 × 6 - 2 + 8 = 24 - 2 + 8 = 30, which is correct.
