This determinant calculator can help you calculate the determinant of a square matrix independent of its type in regard of the number of columns and rows (2x2, 3x3 or 4x4). You can get all the formulas used right after the tool.

## How does this determinant calculator work?

This determinant calculator can assist you when calculating the matrix determinant having between 2 and 4 rows and columns. Please note that the tool allows using both positive and negative numbers, with or without decimals and even fractions written using "/" sign (for instance 1/2).

In algebra the determinant (usually written as det(A)) represents a value computed from the entries of a given square matrix (which has the same number of rows and columns) which is further on used in different matrix calculations (e.g finding the right solutions of a linear system of equations).

Below there are the formulas used to compute the determinant depending on the matrix ordin:

### Matrix determinant 2x2 formula

### Matrix determinant 3x3 formula

### Matrix determinant 4x4 formula
