Today, math enthusiasts around the world celebrate the mysteriously long number, Pi, which has been calculated to over 1 trillion digits passed the decimal. The Greek letter represents the ratio of the circumference of a circle to its diameter and has roused an annual celebration on 3/14 for the past four years. Pi is a transcendental and irrational number, meaning it will continue infinitely without repeating, which is why it has confused yet fascinated mathematicians for centuries.

For years, Pi Day has been bringing fun to math classrooms as well as admitted math geeks around the world. Even those who are not typically excited over math equations often take part in the celebration, for example, by eating pie! There is an endless amount of ways to take part in the celebration. For example, take on a Pi Day Challenge or send an E-card to a friend. If you’re looking for more unique ways to celebrate, check out how some enthusiasts spent last year’s Pi Day!
