What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–’ are interchanged and ‘×’ and ‘÷’ are interchanged? 4 – 5 + 9 ÷ 6 × 2 = ?
-18
To solve this problem, we need to first apply the given symbol interchanges to the equation:
- ‘+’ and ‘–’ are interchanged.
- ‘×’ and ‘÷’ are interchanged.
Given equation: 4 – 5 + 9 ÷ 6 × 2 = ?
After interchanging the symbols, the equation becomes:
4 + 5 – 9 × 6 ÷ 2 = ?
Now, solve the equation using the correct order of operations (PEMDAS/BODMAS):
- Division: Calculate 6 ÷ 2 = 3.
- Multiplication: Calculate 9 × 3 = 27.
- Addition: Calculate 4 + 5 = 9.
- Subtraction: Calculate 9 – 27 = –18.
Thus, the result of the equation is –18.
