Question

8. To calculate 159 - 73, a student writes the following equations: 160 - 70 = 90 - 3 = 87 - 1 = 86 Although the student has a good idea for solving the problem, his equations are not correct. In words, describe the student's solution strategy and discuss why the strategy makes sense; then write a correct sequence of equations that correspond to this solution strategy. Write your equations in the following form: 159 - 73 = some expression = some expression = : = 86
