Learn from worked examples
A worked solution can show the reasoning between the question and the answer. Inspecting each step is different from copying the final line and assuming the method is understood.

A worked example
For 3x + 4 = 19, ask why subtracting four from both sides preserves equality. Then ask why dividing both sides by three isolates x. Cover the solution and solve 3x + 4 = 22. Substituting the new answer back into the equation checks the result and the interpretation of x.
Try it in three steps
- Explain the purpose of each step.
- Cover the example and try a related problem.
- Compare the reasoning, not only the final answer.
What to watch for
A worked example may rely on assumptions or prior knowledge. Identify unfamiliar steps and check them before extending the method.
Apply it to your own material
Choose one topic from your current course or project. Write down the question you want to answer, make an attempt, and keep a note of how you checked it. Use the example above as a pattern; replace its subject matter and assumptions rather than copying an answer into a different task.
