Multiplication of matrix with scalar

WebThe properties of scalar multiplication of a matrix are defined by two matrices of the same order. Let us say, A = [a ij] and B = [b ij] are two matrices of the same order, say m × n. Also, the two scalars are k and l. Then the scalar multiplication are given by: k (A + B) = kA + kB (k + l)A = k A + l A Let us find how we got the above equation.
