Matrix Addition & Subtraction Calculator

Add or subtract two same-size matrices element by element. Toggle between sum and difference and view the result as a table.

For two matrices A and B of the same size, the sum is C[i][j] = A[i][j] + B[i][j] and the difference is C[i][j] = A[i][j] − B[i][j]; corresponding entries are added or subtracted element by element.
Each input line is one row of the matrix, and entries in a row are separated by spaces, tabs, or commas. Blank lines are ignored.
Addition and subtraction are only defined when matrix A and matrix B have the same dimensions (rows × columns); mismatched sizes produce an error.
If the rows of a matrix do not all have the same number of entries (columns), an error is shown. Keep every row the same width.
