Determinant calculation by expanding it on a line or a column, using Laplace's formula.

This page allows to find the determinant of a matrix using row reductions or expansion by minors.

Matrix A:
  • leave extra cells empty to enter non-square matrices
  • you can use decimal (finite and periodic) fractions: 1/3, 3.14, -1.3(56), 1.2e-4 ; or arithmetic expressions: 2/3+3*(10-4), (1+x)/y^2, 2^0.5
  • use ↵ Enter, Space, , , , to navigate between cells
  • drag-and-drop matrices from the results, or even from/to a text editor
  • to learn more about matrices use WikipediA.
