Addition of Matrices Matrices may only be added if the both have the same dimensions. To add two matrices, each element is added to its correyponding element. The sum matrix has the same dimensions as the two being added. Example: Add matrix A to Matrix B 6 2 6 2 1 3 A- B 0 -3 6 Solution : 6+2 2+1 6 t 3 A +B - to 3-3 of L d 3 9 - 0 6 Multiplication of a Scalar and Matrix When multiplying a matrix by a scalar (or number). we write "scalar k times matrix A. "Each element of the matrix is multiplied by the scalar. By Example: 2 3 K = 3 and A- 7 Dd:

Date then 2 3 3 x A - 3 I 7 2.3 3.3 - 1.3 7.3 6 9 - 3 21 CS Dipindai dengan CamScanner
