Two matrices can only be multiplied if the number of columns of the matrix on the left is the same as the number of rows of the matrix on the right. The first row “hits” the first column, giving us the first entry of the product. Different operations like the addition of matrices, subtraction of matrices, scalar multiplication of matrices, multiplication of matrices, transpose of a matrix etc can be performed on matrices.as we scroll down, we will learn about matrix multiplication, multiplication of two and three matrices, matrix multiplication rules, how to multiply matrices and more with solved.
