Answer:
The features of a strong math explanation include the following:
1. Step-by-step reasoning: A key trait is providing a sequential solution. Don't omit steps since assuming the reader understands skipped parts can be incorrect.
2. Justify every step: Explain why each step is taken, for example by citing a theorem, formula, or rule.
3. Check the result: Once you obtain an answer, the final action is to confirm it.
Verify whether the solution meets the given conditions; if it does, it's correct, otherwise revisit your work.
