3.14159.

Pretty boring number, right? Not if you’re a math and science enthusiast. If you’re into numbers, it’s pi, an irrational and transcendental number with more than a trillion digits after its decimal point. But when you round it off to just two numbers after its decimal point, it’s 3.14 — or March 14 — which just so happens to be Albert Einstein’s birthday.

Since math and science nerds rule the world, there is, of course, a National Pi Day. And National Pi Day, of course, is on March 14. Not wanting to miss out on the action, businesses of all kinds offer deals, discounts and freebies on Pi Day. Here are just a few ways to score deals on things like cheap pie and cheap pizza this year.
