Answer:
C. 22
Read Explanation:
Based on the steps provided, the original mathematical expression is:
$41 - [21 - \{11 - (15 - \frac{9}{3} \times 2)\}]$
Step 1 (Innermost Parentheses):
Evaluate $15 - \frac{9}{3} \times 2$
Divide first: $\frac{9}{3} = 3$
Multiply next: $3 \times 2 = 6$
Subtract last: $15 - 6 = \mathbf{9}$Step 2 (Curly Brackets):
Evaluate $11 - 9 = \mathbf{2}$Step 3 (Square Brackets):
Evaluate $21 - 2 = \mathbf{1 9}$Step 4 (Final Calculation):
Evaluate $41 - 19 = \mathbf{22}$
The value of the expression is 22.
