User Portlet

I am a novice user. Many moons ago, I taught senior high algebra at a time when graphical calculators were first being introduced, but prior to the integration into the curriculum of computers and sophisticated mathematical and modeling software. I purchased Mathematica 9.0 Home Edition during Wolfram's 25th Anniversary offer in August 2013. I will be a recreational user. My areas of interest are number theory, geometry and fractals.
