Can you multiply Matrices?

To multiply matrices we have to:

1. We have to write a dimension statement to see whether or not the matrix can be multiplied.
2. If it can be multiplied then we multiply ROW x COLUMN.
3. Then get the sum of the product.

Dimension Statement Example:
[2   3] [-6]
[4   7] [-8]

Dimension Statement: 2 x 2 times 2 x 1

The numbers in green tell you whether or not the matrix can be multiplied, in this case they can be multiplied because the numbers are the same.
The numbers in blue tell you the size of the final answer.
