In linear algebra homework, matrices and systems often look cramped or the brackets don’t match the height. amsmath matrix and alignment environments exist for that. You can also sketch the skeleton in NovaMath, then copy LaTeX.
Which matrix environment
pmatrix— round brackets (default pick)bmatrix— square bracketsvmatrix/Vmatrix— determinantsmatrix— no fences; nest inside something larger
Columns with &, new rows with \\. Get the shape right before filling numbers.
Systems
Use align / align* and put & before =. Cleaner than stacking separate display equations. Piecewise: cases, with condition text in \text{}.
Practice order
- Insert a (2\times 2) or (3\times 3) template in the editor.
- Swap in homework numbers; check bracket height.
- Paste into the report; on errors, check

Correct structure beats pretty fonts. For linear-transform intuition, open visualization.
