Evaluate: \(20 - [10 - \{8 - (6 - 2)\}]\)
Answer: B
Using the order of operations (BODMAS/PEMDAS):
Step 1: Solve the innermost bracket: \((6 - 2) = 4\).
Step 2: Solve the curly bracket: \(\{8 - 4\} = 4\).
Step 3: Solve the square bracket: \([10 - 4] = 6\).
Step 4: Perform the final subtraction: \(20 - 6 = 14\).
