A personal message from the author:

I am a current high school junior at The Waterford School in Sandy, Utah. I discovered the beauty of math at a very early age and love every aspect of it to this day. Even more than learning, I enjoy teaching math to younger students and watching their passion grow over time. In the future, I hope to have a career in the mathematics field. Math really does not have to be hard, and your teacher is always there to help you. Find help in your teacher and destroy your monster!

Also, all proceeds will be donated to organizations that are truly in need. Learn how to do addition and know that you are supporting great causes!
