9. To calculate 201 – 88, a student writes the following equations: 88 + 2 = 90 + 10 = 100 + 100 = 200 + 1 2 + 10 = 12 + 100 = 112 + 1 = 113 = 201 = Although the student has a good idea for solving the problem, their equations are not correct. In words, describe the student's solution strategy and explain why it makes sense; then write correct equations that correspond to this solution strategy.
