How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

A 2×2 matrix has entries a, b, c, d. Determinant = ad − bc. Inverse (if det ≠ 0) = (1/det) × [[d,−b],[−c,a]]. Used in linear algebra, transformations, and systems of equations.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

What is a determinant?

The determinant of a 2×2 matrix [[a,b],[c,d]] = ad − bc. If det = 0, the matrix is singular and has no inverse. It measures the scaling factor of the linear transformation.
