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.

'; explain[2] = '#3

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

'; explain[3] = '#4

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

'; explain[4] = '#5

Matrices do not add different positions together during an addition function.
