  2. Input Formatting:
    Use commas , for separating columns and semicolons ; for rows to avoid errors.
  3. Use Scalars Strategically:
    Multiplying by a scalar can simplify calculations, scale a dataset, or adjust matrix values efficiently.
  4. Verify Results:
    For critical calculations, cross-check the output, especially with large matrices, to ensure accuracy.
  5. Experiment with Operations:
    Test different operations to see relationships between matrices, which can help in learning linear algebra concepts.
