The following equation is incorrect. Which two signs should be interchanged to make it correct? $18 - 6 \times 20 \div 5 + 3 = 58$

1. + and -
2. × and -
3. - and ÷
4. ÷ and ×

Correct answer: - and ÷

Solution

Interchanging $-$ and $\div$ gives $18 \div 6 \times 20 - 5 + 3$. Evaluating left to right for multiplication and division: $18 \div 6 = 3$, $3 \times 20 = 60$, and $60 - 5 + 3 = 58$.
