Napier's Gift

I was inspired by the first chapter of Eli Maor's e:The Story of a Number to create this GeoGebra applet designed to help the user discover how to simplify the process of finding a quotient by subtracting exponents. The idea is both to introduce students to logarithms (though they are never mentioned explicitly) and to help students understand why they were so heralded when they were introduced. The applet is also posted on GeoGebraTube.
