Matrix A

2 × 2

RowsColumns

Paste values

One row per line; separate entries with commas or tabs.

Matrix B

2 × 2

RowsColumns

Paste values

One row per line; separate entries with commas or tabs.

Operation

Enter numbers, fractions or expressions such as 1/3 and sqrt(2). Blank cells are zero. Up to 10 × 10.

Result

Results use floating-point arithmetic and display up to 10 significant digits.

Get started

Create a matrix, choose its dimensions and enter the values. Use the available operations to multiply matrices, calculate a determinant or find an inverse.

Try A = [[1, 2], [3, 4]], then det(A) = −2
