Replace the letters with mathematical operators and solve using BODMAS (Divide, Multiply, Add, Subtract) to find the result.
Replace the letters with mathematical operators and solve using BODMAS (Divide, Multiply, Add, Subtract) to find the result.
Substitution
Replace letters with operations: A=+, B=-, C=×, D=÷. The equation becomes: 14 ÷ 2 + 10 - 3 × 5
BODMAS Application
Follow BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction). First, divide: 14 ÷ 2 = 7. Second, multiply: 3 × 5 = 15.
Final Calculation
The expression is now 7 + 10 - 15. Perform addition: 7 + 10 = 17. Perform subtraction: 17 - 15 = 2.
A: 1 is incorrect because the result is 2. B: 3 is incorrect as the calculated value matches Option C. D: 0 is incorrect.
C is correct because applying BODMAS rules to the expression 14 / 2 + 10−3∗5yields 7 + 10−15 = 2.
Always handle Division and Multiplication first in such problems to avoid common errors; treat the equation as a single line after substitution.
