79 D 12 B 4 C 100 A 5 = ?
Solve Symbolic Equation: Step-by-Step Calculation
The problem requires substituting given symbols with mathematical operators and then evaluating the resulting expression using the standard order of operations (BODMAS/PEMDAS).
1. Substitution Phase
Identify the operators corresponding to each letter:
- 'A' = '÷'
- 'B' = 'x'
- 'C' = '+'
- 'D' = '-'
Substitute these operators into the given equation:
Original: \(79 D 12 B 4 C 100 A 5\)
After substitution: \(79 - 12 x 4 + 100 ÷ 5\)
2. Calculation Phase (Order of Operations)
Evaluate the expression following BODMAS/PEMDAS:
- Division: Calculate \(100 ÷ 5\)
\( 100 \div 5 = 20 \)
- Multiplication: Calculate \(12 x 4\)
\( 12 \times 4 = 48 \)
- The expression now is: \(79 - 48 + 20\)
- Subtraction (left to right): Calculate \(79 - 48\)
\( 79 - 48 = 31 \)
- Addition: Calculate \(31 + 20\)
\( 31 + 20 = 51 \)
3. Final Result
The value of the expression is 51.
