In this video, we develop the process behind the multiplication of 2 matrices. We discover how we start with one matrix of certain dimensions, multiply it by another matrix of different dimensions and produce a new matrix that has yet different dimensions to the first two.
The example we will use to develop the theory is running a fruit stall where we have a matrix P derived from a table that lists the quantities of each fruit in each package. We also have a matrix M, which is derived from a table that lists how many of each package we sold in the months of July, August and September.
We multiply the matrices M x P to get the total quantities of each fruit that were sold in the months of July, August and September.
Thanks for watching. Please give me an "upvote" if you have found this video helpful.
