Answer 2

To calculate the expression, follow the order of operations (PEMDAS/BODMAS):

P: Parentheses first E: Exponents (none in this case) MD: Multiplication and Division (none in this case) AS: Addition and Subtraction

The expression is: 42 - (14.15 + 23.42) - 1.725

Step 1: Evaluate the expression inside the parentheses: 14.15 + 23.42 = 37.57

Step 2: Substitute the result back into the main expression: 42 - 37.57 - 1.725

Step 3: Perform the subtraction: 42 - 37.57 = 4.43

Step 4: Subtract the final number: 4.43 - 1.725 ≈ 2.705

The result of the expression is approximately 2.705.
