## Quick Answer

Perform matrix arithmetic and calculations. Enter your matrix values to compute determinants, transposes, inverses, and products.

## Definition

A matrix calculator performs fundamental linear algebra operations on two-dimensional arrays of numbers, specifically supporting two-by-two and three-by-three matrices. The tool calculates matrix addition, subtraction, scalar multiplication, matrix multiplication, determinants, transposes, and matrix inverses. Linear algebra students, engineers, and computer graphics programmers use this utility to verify matrix arithmetic, solve transformation matrices, and check computational models without performing tedious manual row and column operations.

## How to Use

1. **Select matrix operation** — Choose the matrix calculation you wish to perform, such as multiplication or finding an inverse.
2. **Enter matrix dimensions** — Type the values for matrix A and matrix B in the grids.
3. **Read the matrix result** — View the resulting matrix array, including the determinant and inverse step-by-step steps.
