Companies are offering deals and discounts on pizza, pie, and more in honor of Pi Day 2020.

Now is as good a time as any to celebrate something fun and frivolous. Yes, I am talking about Pi Day, a pseudo-holiday in honor of the irrational number pi. What better way to honor such an occasion than with a bunch of Pi Day 2020 deals and freebies. Discounts involve percentages! Zero is a number! Wow, you’re doing math already!

If you’re asking yourself, “what even is pi?”, welcome. I come bearing gifts of easy-to-understand explanations of mathematics. Pi— represented by the fraction 22/7 or the rounded decimal 3.14 or the symbol Π if you’re nasty—is a mathematical constant. You likely know pi from geometry class as its most well-known definition is “the ratio of a circle's circumference to its diameter.” Pi is also known best as an “infinite decimal,” meaning the digits after the decimal point go on forever. While mathematicians don’t know every digit of pi—it would be essentially impossible to do so as the digits go on forever—they have tried to calculate as many digits as possible. In 2019, Emma Haruko Iwao, a Google employee from Japan, set a new world record for calculating the digits of Pi. Previously, the record for was 22 trillion calculated digits of Pi. Iwao was able to calculate 31 trillion digits.

March 14 is Pi Day because of how the date is represented on American calendars: 3-14. If you wanna get really specific, the most pi part of Pi Day is March 14 at 1:59 and 26 seconds as the first eight digits of pie are 3.1415926. Now that you’ve worked up an appetite thinking about math, here are 24 Pi Day deals and freebies you can enjoy even if you can’t recite thousands of digits of an irrational number.
