Addition and Subtraction of Matrices.

In this Video, we explain the basic steps required to work out simple addition and subtraction of Matrices.
Matrices can only be added or substracted if they are of thesame form. Therefore a 3×4 matrix can only be added to or substracted another 3×4 matrix.
Scalar Multiplication of Matrices involve the use of real numbers to scale or Multiply with Vectors (in this case; Matrices).
Enjoy.
