Do you like pi? How about pie? Why are we asking this? Well, because National Pi Day is upon us.

The day, celebrated on March 14 — get it? 3/14 — each year, comes in honor of pi, as in, the 16th letter of the Greek alphabet. Remember pi from math class? It’s used to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. (Thanks, PiDay.org for the reminder!)

Anyway, now you know why we have Pi Day. But do you know how to celebrate Pi Day? With some discounted pies, of course!
