WATCH What is Pi Day?

Happy Pi Day! While math nerds may have March 14 — 3/14 — circled on their calendars for the annual celebration of that quantity with an infinite number of decimal digits, it's a day of deals that everyone can enjoy.

Recently Pi Day has become a fun way for companies to promote deep discounts on products from pies to PCs. Pi is the ratio of a circle's circumference to its diameter, but on March 14, the mathematical symbol is more of a sign for savings.
