Matrix Calculator
Matrix — matrix Calculator performs the matrix operation (add, multiply or transpose) element by element following the rules of linear algebra. This page runs that same calculation on your numbers, in your browser: no signup, no uploads, nothing stored.
Matrix Calculator lets you work through a calculation in seconds: enter your matrix A, operation and matrix B for the result, all worked out locally in your browser.
About this calculator
Get matrix right and the rest of the task gets easier. Matrix Calculator performs the matrix operation (add, multiply or transpose) element by element following the rules of linear algebra. It matters when you need the exact relationship checked quickly rather than worked through by hand. Adding [[1,2],[3,4]] + [[5,6],[7,8]] adds element by element to give [[6,8],[10,12]] . The tool above does the same computation in your browser — free, private, nothing stored.
How to use
- Type Matrix A, with rows separated by semicolons or new lines and values by commas.
- Choose an operation: determinant, inverse, transpose, add, subtract, or multiply.
- For add, subtract, or multiply, also type Matrix B, then press Calculate.
- Read the resulting matrix or value below.

FAQ
Which operations does the Matrix Calculator support?
It computes the determinant, inverse, and transpose of Matrix A, and the sum, difference, or product of Matrix A and Matrix B.
When do I need to fill in Matrix B?
Matrix B is only needed for add, subtract, and multiply. Determinant, inverse, and transpose use Matrix A alone.
What sizes must A and B be?
Addition and subtraction need A and B to be the same size; multiplication needs the columns of A to equal the rows of B. Mismatches are flagged.
Does the Matrix Calculator send my data to a server?
No. The Matrix Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
Adding [[1,2],[3,4]] + [[5,6],[7,8]] adds element by element to give [[6,8],[10,12]].
