I liked how easy the tools was to use. It enables students to enter two of
three quantities and the third is calculated for them.
If I were to suggest something it would be for students entering a percentage
and whole the pie chart would equal divisions summing to the whole (e.g.
percentage = 30, whole = 100; the pie chart would display 10 equal sections with
"10" enclosed to visually represent the part = 30 in one color and 7 other
sections of a lighter color displaying the remaining percentage).
