Answer 2

Calculation:

To solve the expression 21.4 - 5 + 1/2 - (16 + 2/3 - 6.6), we can follow the order of operations (PEMDAS/BODMAS) to simplify the expression step by step.

1. First, let's simplify the expression inside the parentheses: - (16 + 2/3 - 6.6) = 16 + 2/3 - 6.6.

2. Next, let's simplify the addition and subtraction inside the parentheses: - 16 + 2/3 - 6.6 = 16 + 0.6667 - 6.6.

3. Now, let's simplify the addition and subtraction outside the parentheses: - 21.4 - 5 + 1/2 - (16 + 2/3 - 6.6) = 21.4 - 5 + 1/2 - (16 + 0.6667 - 6.6).

4. Finally, let's perform the remaining addition and subtraction: - 21.4 - 5 + 1/2 - (16 + 0.6667 - 6.6) = 21.4 - 5 + 1/2 - 10.0667.

To get the final result, we can calculate the expression using a calculator or Python code.
