What will come in the place of the question mark (?) in the following equation, if '+' and '-' are interchanged and 'x' and '÷' are
interchanged?
$98 \times 14 + 24 - 12 \div 8 = ?$
Understanding the Operator Interchange Problem
The question asks us to find the value of the given mathematical expression after applying specific rules for interchanging operators. We need to swap '+' with '-' and 'x' with '÷'. The original equation is:
$$98 \times 14 + 24 - 12 \div 8 = ?$$
The rules for interchanging operators are:
- '+' becomes '-'
- '-' becomes '+'
- 'x' becomes '÷'
- '÷' becomes 'x'
Transforming the Equation Based on Operator Interchange
Let's apply these interchange rules to the original equation:
- The multiplication symbol '
×' will be replaced by the division symbol '÷'. - The addition symbol '
+' will be replaced by the subtraction symbol '-'. - The subtraction symbol '
-' will be replaced by the addition symbol '+'. - The division symbol '
÷' will be replaced by the multiplication symbol '×'.
Applying these changes, the equation becomes:
$$98 \div 14 - 24 + 12 \times 8 = ?$$
Step-by-Step Solution Using BODMAS Rule
Now, we need to solve the transformed equation using the standard order of operations (BODMAS/PEMDAS), which stands for Brackets, Orders (powers/roots), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).
- Division: First, perform the division operation. $$98 \div 14 = 7$$
- Multiplication: Next, perform the multiplication operation. $$12 \times 8 = 96$$
- Rewrite Equation: Substitute the results back into the equation. $$7 - 24 + 96 = ?$$
- Subtraction: Perform the subtraction from left to right. $$7 - 24 = -17$$
- Addition: Finally, perform the addition. $$-17 + 96 = 79$$
Therefore, the value that comes in the place of the question mark is 79.
Final Answer
The value of the equation after interchanging the operators is 79.
