# Calculator for 2x2 determinants

## Online Calculator for Determinant 2x2

The online calculator calculates the value of the determinant of a 2x2 matrix.

### Determinant 2x2

$\mathrm{det A}=|\begin{array}{cc}{a}_{11}& {a}_{12}\\ {a}_{21}& {a}_{22}\end{array}|={a}_{11}\cdot {a}_{22}-\left({a}_{21}\cdot {a}_{12}\right)$

Enter the coefficients:

a11= a12=

a21= a22=

Calculated determinant:

The main diagonal elements are colored green and the scondary diagonal elements are shown in blue color.
