Beth decided to first subtract 1 from both numbers when she was calculating \( 23000-4977 \). a. Write down the new problem and solve it. Explain why Beth would use this method.

Calculate or simplify the expression \( 23000-4977 \). Calculate the value by following steps: - step0: Calculate: \(23000-4977\) - step1: Subtract the numbers: \(18023\) The new problem after subtracting 1 from both numbers is \( 23000-1-4977-1 \). Let's solve this new problem: \( 23000-1-4977-1 = 23000-1-4977-1 = 18023 \) Beth would use this method because subtracting 1 from both numbers is equivalent to subtracting 2 from the original number. This method simplifies the calculation and makes it easier to perform the subtraction.
