Equation Transformation
The given equation is:
\(70 Q 2 R 5 P 3 S 18 = ?\)
Substituting the symbols:
\(70 ÷ 2 - 5 × 3 + 18 = ?\)
Step-by-Step Calculation using BODMAS
We use the order of operations (BODMAS/PEMDAS: Brackets, Orders, Division/Multiplication, Addition/Subtraction) to solve the equation.
- Division: Perform the division first.
\( 70 \div 2 = 35 \)
The equation becomes: \(35 - 5 × 3 + 18 = ?\)
- Multiplication: Perform the multiplication next.
\( 5 \times 3 = 15 \)
The equation becomes: \(35 - 15 + 18 = ?\)
- Addition/Subtraction: Perform subtraction and addition from left to right.
First, subtraction: \( 35 - 15 = 20 \)
Then, addition: \( 20 + 18 = 38 \)
Therefore, the value of the equation is 38.
