Important notes The number of columns in the first matrix must be the same as the number of rows in the second matrix for it to be defined. The resulting matrix dimensions will be the number of rows in the first matrix by the number of columns in the second matrix. Matrix multiplication does not commute. Properties of matrix multiplication. Order of operations
