How to review math mistakes
Keep four things in your error log: the problem, your original work, your first wrong step, and what happened when you tried again.
Save the problem and your work
Include the full question, any diagrams, and the steps you actually wrote. If several problems went wrong in the same way, start with one representative example.
Find the first wrong step
Read your work from the beginning. Circle the first step that changes the problem incorrectly, then write a reminder you can use next time.
Try it again with the solution covered
Try the same problem the next day and mark it “solved on my own,” “solved with a hint,” or “still stuck.” Put the last two groups at the top of your next review. Check this example by substituting 6 into the original equation.
