While Multiplication and Division functions of Matrices result in a Matrix that is not necessarily the same dimensions, Adding and Subtraction functions will result with a matrix of the same dimension.

When Multiplying Matrices, they usually are not of the same dimensions. You can not always multiply Matices of the same dimensions.

Matrices can be multiplied by variables or constants. It results in each term being multiplied.

Just as Matrices can be added, they can also be subtracted, the process is the same as adding.
