Calculate the determinant of a square matrix and see whether the matrix is singular or invertible.
Last updated: June 2026 | By Patchworkr Team
The determinant is a scalar value associated with a square matrix. It reveals whether the matrix is invertible and describes how the transformation scales area or volume.
For [[3, 8], [4, 6]], the determinant is -14.
What does a determinant of 0 mean?
A zero determinant means the matrix is singular and has no inverse.
Can a determinant be negative?
Yes. A negative determinant usually indicates an orientation reversal in the transformation.
Does this calculator accept decimals?
Yes. Any finite real matrix entries are accepted, including decimal and scientific notation values.
What if a cell is blank?
Blank cells are rejected instead of being silently converted to zero.
