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.
