No other number is quite like 3.14. That’s pi — and it’s actually a drastically abbreviated version of a number that is believed to have more than 1 trillion digits following the decimal point. Used to calculate the ratio of a circle’s circumference to its diameter, pi is one of the most important numbers and symbols for mathletes worldwide — but it also holds symbolic meaning. The number 3.14 corresponds to March 14, which is Pi Day — and coincidentally enough, the birthday of math and science god Albert Einstein.
In honor of the special number, businesses, stores and restaurants across the country offer discount food and other merchandise on and around March 14. Here’s how you can save money on food this Pi Day.
