Another important **Tip** for students taking **GCE O Level Elementary Mathe (E-Math)**:

Unlike multiplication of numbers, multiplication of matrix requires some prep work.

- First, you have to
**check the feasibility**of the 2 Matrices which you are multiplying together. You must know the**order of each matrix**i.e Number of Rows x Number of Columns (I always call it RC, Resident Committee, Remote Control etc...) - Next, you have to know the
**order of your answer**before you go ahead and find the answers.

I am using the following question to illustrate **How To Multiply Matrix** step by step.
