Add, multiply and compute a determinant. Handy for students, analysts and engineers checking a calculation or conversion before using the result.
Add, multiply and compute a determinant. See a clear result update immediately in your browser, with no account, upload or stored data to worry about.
In the sample input, the tool should add two 2 by 2 matrices. Look at the resulting matrix row by row; this helps you confirm the expected format before working with larger matrices.
The matrices you enter are processed locally in your browser. Nothing is sent out, no account is required, and the content is not stored after use.
Write one matrix row per line, separating numbers with spaces. For addition or multiplication, place two dashes on a line by themselves, then enter the second matrix in the same way.
The tool offers addition, multiplication and determinant. Type add, mul or det on the first line, then provide the matrix or matrices required by that operation.
Check that the operation name is spelled correctly, that each row has the same number of values, and that the matrices have the required dimensions. Non-numeric characters or irregular separators can block the calculation.
No. A determinant only applies to square matrices. Matrix dimensions must be compatible with the chosen operation. For a determinant, enter det on the first line, then provide a square matrix A with one row per line and values separated by spaces. If the dimensions are wrong, the calculation may fail.
No. The matrices you enter are processed locally in your browser. Nothing is sent out, no account is required, and the content is not stored after use. You can clear the area to test another operation. If you need the result, copy it before leaving the page.
