Matrix Calculator
Use this matrix calculator to work through common matrix operations in algebra and introductory linear algebra.
It supports square 2x2 and 3x3 matrices for addition, subtraction, multiplication, and determinant calculations.
That makes it helpful for classroom review without needing advanced software.
The layout keeps both matrices visible so you can compare each step more easily.
Matrix A
Matrix B
| Row 1 | 3, 2 | |
|---|---|---|
| Row 2 | 4, 6 | |
Assumptions
- This page is designed for square 2x2 and 3x3 classroom matrices.
- Determinant mode uses matrix A only.
- For large matrices or symbolic matrix algebra, use specialized software.
How this calculator works
Formula used
Matrix addition and subtraction combine matching positions, multiplication uses row-by-column products, and determinant follows standard square-matrix rules.
Example calculation
Multiplying [[1, 2], [3, 4]] by [[2, 0], [1, 2]] returns [[4, 4], [10, 8]].
