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 reduction, expansion by minors, or Leibniz formula.

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), or 1.2e-4; or arithmetic expressions: 2/3+3*(10-4), (1+x)/y^2, 2^0.5 (=2), 2^(1/3), 2^n, sin(phi), or cos(3.142rad).
  • Use ↵ Enter, Space, ←↑↓→, ⌫, and Delete to navigate between cells, Ctrl⌘ Cmd+C/Ctrl⌘ Cmd+V to copy/paste matrices.
  • Drag-and-drop matrices from the results, or even from/to a text editor.
  • To learn more about matrices use Wikipedia.
