Frequently Asked Questions

What is matrix addition?

Matrix addition is the operation of adding two matrices by adding the corresponding entries together. For addition to be defined, both matrices must have the same dimensions.

How does matrix multiplication work?

Matrix multiplication involves multiplying rows of the first matrix by columns of the second matrix. The number of columns in the first matrix must equal the number of rows in the second matrix for multiplication to be possible.

What does the determinant tell us?

The determinant of a square matrix is a special number that provides important information about the matrix. It can tell you if the matrix is invertible, and it's used in solving systems of linear equations, among other applications.

Is there a size limit for matrices?

Our calculator supports matrices up to 5x5 to ensure fast performance in your browser. For larger matrices, we recommend specialized software.
