Day one

Welcome mathletes!

I'm excited to begin our mathletic training! This blog can only exist if you contribute with your questions and comments, so don't hesitate to e-mail me mathletictrainer@gmail.com. I will be posting and answering your questions as often as I am able, so please send them in!

This blog will feature:

  • YOUR questions and problems.
  • MY coaching to get you through that tough math problem or difficult concept.
  • A math Question of the Day to get your math muscles warmed up.
  • A featured Mathematician of the Month so you can learn about the great minds behind the art of mathematics.
