How matrices are subtracted
Subtract the numbers in the same position. For A = [[5, 6], [7, 8]] and B = [[1, 2], [3, 4]], A − B = [[4, 4], [4, 4]]. Note that A − B is not the same as B − A: every sign flips.
Both matrices need the same size. Fractions are allowed and the result is exact. To add, use the matrix addition calculator.
