I hope that those who have not considered this
alternative method will see the possible advantages for
themselves and their students. First, this method may
increase the accessibility of matrix material for
students with weaknesses in fractions. Next, the
method has the potential to increase the speed and
accuracy of computations for students and teachers
alike by the substitution of integer computations for
rational number computations. I have found that some
students avoid fractions by using decimal
approximations, sacrificing precision. However, with
this method, teachers can still require the precision of
fractional solutions without the excessive mire of
fractions, potentially encouraging more student effort
and success. Finally, teachers who are wary of
requiring extensive fractional computations may be
freed by this method to have a greater flexibility in
problem selection.
