At that time, I thought the interface was the best yet, the videos fun and
informative. I thought it fell short in sticking to the traditional
integer model. The points plotted in graphing had integer coefficients,
the scaling was generally even and a "-10 to 10" scale and coefficients of
problems were generally small integers. The program at that time did not
seem to take us to a mathematics that we can't do just as well with pencil
and paper.
The concept of the function machine was good.
