$*$ post: This method should not alter the calling object or rightHandSide

$*$ @param rightHandSide rightHandSide.getNumRows$()=$ getNumColumns$()$

$*$ @return a new MathMatrix that is the result of multiplying

$*$ this MathMatrix and rightHandSide.

$*$ The number of rows in the returned MathMatrix is equal to the number of rows

$*$ in this MathMatrix. The number of columns in the returned MathMatrix is equal to the number

$*$ of columns in rightHandSide.
