Question

Evaluate: 2 × {17 - 3 × (9 -5)}

• A. 14
• B. 9
• C. 10
• D. 7

Answer 1

Answer:

C. 10

2 × {17 - 3 × (9 - 5)} = 10

Following the BODMAS / PEMDAS rule, we solve from the innermost brackets outward:

• Step 1: Solve the operations inside the round parentheses $( )$:
  $9 - 5 = 4$
  Now the expression becomes: $2 \times \{17 - 3 \times 4\}$

• Step 2: Solve the multiplication inside the curly braces $\{ \}$:
  $3 \times 4 = 12$
  Now the expression becomes: $2 \times \{17 - 12\}$

• Step 3: Solve the subtraction inside the curly braces $\{ \}$:
  $17 - 12 = 5$
  Now the expression becomes: $2 \times 5$

• Step 4: Perform the final multiplication:
  $2 \times 5 = 10$
