Apply BODMAS rules sequentially: Division, Multiplication, Addition, and then Subtraction to resolve the operators in one go.
Apply BODMAS rules sequentially: Division, Multiplication, Addition, and then Subtraction to resolve the operators in one go.
Symbol Replacement
Replace the symbols in the expression 25% 2 # 8 10 @ 5 \text{based on given rules}: \% = *, # = -, = +, @ = /. The expression becomes: 25 * 2 - 8 + 10 / 5.
BODMAS Application
Solve following BODMAS: 1. Division: 10 / 5 = 2. 2. Multiplication: 25 * 2 = 50. The equation is now 50 - 8 + 2.
Final Calculation
Perform Addition and Subtraction: 50 + 2 = 52, then 52 - 8 = 44.
A: Results from incorrectly calculating 50 - (8+2) which equals 40, not 45. C: Results from calculating 50 - 8 + 4, which is 46, assuming 10/5 is 4. D: Results from calculating 50 - 7, assuming an error in the final subtraction step.
B is correct because replacing the symbols yields 50 - 8 + 2, which equals 44 following BODMAS rules.
Always perform division and multiplication operations first before addition and subtraction to avoid common errors in multi-step equations.
