Answer 2

To determine where to place the parentheses in the expression 42-17-11+9=5, we need to follow the standard order of operations (PEMDAS/BODMAS). The order of operations is as follows:

1. Parentheses or Brackets
2. Exponents or Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's consider different options for placing the parentheses:

Option 1: (42-17)-(11+9) = 25 - 20 = 5 Option 2: (42-17-11)+9 = 14 + 9 = 23 Option 3: 42-(17-11+9) = 42 - 17 = 25 Option 4: (42-17-11+9) = 23

Only the first option (Option 1: (42-17)-(11+9) = 5) results in the correct answer of 5, which satisfies the equation.
