Help: Matrix Operations
What you need to fill in
- Rows/Columns of matrix A
- The dimensions of the first matrix (up to 6×6).
- Rows/Columns of matrix B
- The dimensions of the second matrix. For multiplication, the columns of A must equal the rows of B.
- Matrix elements
- Fill in each cell of both matrices with its number.
What you'll see in the results
- The resulting matrix of the addition or multiplication
- An error message if the dimensions don't match for the selected operation
The calculation form
Matrix A (2×2)
Frequently asked questions
Matrix multiplication requires the columns of the first matrix to equal the rows of the second. If the dimensions don't match, the operation is not mathematically defined.
For addition, the two matrices must have exactly the same dimensions (the same number of rows and columns).
