Matrix A below has two rows and three columns. The . . of matrix A are 2X3 (two by three; rows then columns). The numbers in the matrix are called . Matrix Multiplication. Matrix multiplication is defined differently than matrix addition. The matrices need not be of the same dimension. Multiplication of the elements will involve both multiplication and addition.
