How to Multiply Matrices

-In order to multiply matrices, you have to first write a dimension statement. This statement states that the columns of the first matrix must match the rows of the other matrix in order for them to be able to be multiplied.

Example of a dimensions statement: 3 x 2and2 x 3

 
These two matrices could not be multiplied because the columns and rows do not match up.
