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:
