Apply the BODMAS rule (Bracket, Of, Division, Multiplication, Addition, Subtraction) strictly after substituting the symbols with their mathematical operators.
Apply the BODMAS rule (Bracket, Of, Division, Multiplication, Addition, Subtraction) strictly after substituting the symbols with their mathematical operators.
Symbol Substitution
Replace the letters with their respective signs: A = /, B = *, C = +, D = -. The equation 3 B 2 D 28 A 7 C 4 becomes 3 * 2 - 28 / 7 + 4.
Applying BODMAS Rule
First, perform division: 28 / 7 = 4. The expression becomes 3 * 2 - 4 + 4. Second, perform multiplication: 3 * 2 = 6. The expression becomes 6 - 4 + 4.
Final Calculation
Solve addition and subtraction from left to right: 6 - 4 = 2, and 2 + 4 = 6.
A: 8 is incorrect because the result is 6. B: 4 is incorrect because the result is 6. C: 12 is incorrect because the result is 6.
D is correct because following the BODMAS rule for the converted expression 3 * 2 - 28 / 7 + 4 results in 6 - 4 + 4 = 6.
In mathematical operations, always prioritize division and multiplication first before moving to addition and subtraction to avoid calculation errors.
