The Equation of Time is an interesting application of conics and composite trigonometric curves.

The equals sign causes a lot of grief. Should we replace it with more meaningful symbols?

Never could master those times tables? This right brain approach might be a solution for you.

Can animals count? How about babies? What is number sense, and counting, all about?

Irrational numbers were a real dilemma for the ancient Greek mathematicians.

Here's a curious type of geometry that leads to a very strange result.

Here's some fun to finish the week. How do these math tricks work?
