Dimension Statements

Before you can begin to multiply matrices you need determine whether or not the matrices can be multiplied. To do that you must write a dimension statement. [3 4] [246][5 6] [7 8 9]
[11 3]
The dimension statement for this would be 3X2 times 2X3.
The numbers on the inside must be the same in order to be able to multiply
The numbers on the outside tell what the dimension of the solution will be. In this particular problem, the solution will be a 3 X 3 matrix.
