x = the number in each matrix cell

y = ** z** multiplied by the square of the number in each matrix cell

z = the number of rows in the 2nd matrix & columns in the 1st matrix

- The number of columns in the 1st matrix must match the number of rows in the 2nd matrix.
- The matrix in the product will have the same number of rows as the 1st matrix & the same number of columns as the 2nd matrix.

Multiplication is commutative with ordinary numbers, but not with matrices because of the way they have to be multiplied...(Do you know how to multiply them? Because of how tricky it is, you'll want to use a calculator!)
