The steps of using mathematics to correct mistakes are as follows: 1. Write down the questions you don't understand and can't do in the math test paper you have done and the workbook you bought during your study. 2. Write the wrong questions in black pen, the steps that can be written in black pen, and the places that can't be written in red pen to highlight the key points. 3. Accumulate at any time, and then take out the corrected book one week later, and do the problem again without looking at the answer.
