7 B 5 D 48 A 4 C 13 = ?
Solving the Equation: Symbol Substitution Method
This question involves replacing given letters with mathematical operators and then evaluating the expression using the standard order of operations (BODMAS/PEMDAS).
Symbol Mapping
First, establish the mapping between the letters and the operators:
- 'A' represents '÷' (Division)
- 'B' represents '×' (Multiplication)
- 'C' represents '+' (Addition)
- 'D' represents '−' (Subtraction)
Equation Transformation
Substitute these operators into the given equation:
Original: $7 B 5 D 48 A 4 C 13 = ?$
After Substitution: $7 \times 5 - 48 \div 4 + 13 = ?$
Applying Order of Operations (BODMAS)
Solve the equation following the BODMAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction).
- Division: Calculate $48 \div 4$.
$48 \div 4 = 12$ - Multiplication: Calculate $7 \times 5$.
$7 \times 5 = 35$
The equation simplifies to:
$35 - 12 + 13 = ?$
- Subtraction (Left to Right): Calculate $35 - 12$.
$35 - 12 = 23$ - Addition (Left to Right): Calculate $23 + 13$.
$23 + 13 = 36$
Result
The final calculated value is 36.
