Introducción
Determinant Calculator — Find the determinant of a 2x2 or 3x3 matrix. Enter a11, a12, a13, a21, a22, a23, a31, a32, a33 to get an instant, accurate result.
Fórmula
2×2: det = ad−bc. 3×3: expanded along the first row via cofactor expansion, det = a(ei−fh) − b(di−fg) + c(dh−eg).

Ejemplo del mundo real
Example: With a11 = 1, a12 = 2, a13 = 3, a21 = 0, a22 = 1, a23 = 4, a31 = 5, a32 = 6, a33 = 0, the Determinant Calculator gives Determinant: 1.
Preguntas Frecuentes
What does a determinant of 0 mean?
The matrix is singular (not invertible) — its rows/columns are linearly dependent.
What matrix sizes are supported?
2×2 and 3×3 matrices.
What inputs does the Determinant Calculator need?
You'll need to provide: a11, a12, a13, a21, a22, a23, a31, a32, a33. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Determinant Calculator?
The Determinant Calculator applies the formula exactly as calculated — 2×2: det = ad−bc. 3×3: expanded along the first row via cofactor expansion, det = a(ei−fh) − b(di−fg) + c(dh−eg). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Determinant Calculator free to use?
Yes, the Determinant Calculator is completely free, requires no signup, and runs instantly in your browser.
Acerca de Calculadora de Determinantes
The Determinant Calculator uses a real, verifiable formula — 2×2: det = ad−bc. 3×3: expanded along the first row via cofactor expansion, det = a(ei−fh) − b(di−fg) + c(dh−eg). — so results are accurate every time, not an approximation.
