The TV show Numb3rs begins each week with:

We all use math every day;
to predict weather, to tell time, to handle money.
Math is more than formulas or equations;
it's logic, it's rationality,
it's using your mind to solve the biggest mysteries we know.

We have developed materials on the mathematics behind each of the episodes of the series. We welcome comments, suggestions, and contributions to these pages. Send them to the project director, Rick Durrett (rtd1(at)

We use the original numbering which is on the DVD. This differs somewhat from the numbers used on the NCTM page.
