To actually multiply you take the first row and multiply by first column and add the resulting products, to get the number to go into column one row one. You will do this process of each space you have to fill alternating the rows and columns.

multiplying matricies
To begin multplying matrices you must first make a deminsion statement. a deminsion stateent is a statemaent that states the deminsions of the two matrices you are multiplying in a certian format.
The deminsion statement is 2x3 times 3x1 you can multiply these matrixes together because the columns of the first matrix matches the rows of the second. the numbers that are not used the 2 and the 1 tell you the deminsions of your anwer.
To actually multiply you take the first row and multiply by first column and add the resulting products, to get the number to go into column one row one. You will do this process of each space you have to fill alternating the rows and columns.
