CELEBRATE PI DAY WITH DISCOUNTS

First of all, Pi is the mathematical ratio of the circumference of a circle to its diameter, which rounds to 3.14, though the full quantity has been calculated to over one trillion digits. “Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern,” explain the Pi Day organizers themselves. “While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.”

In fact, the House of Representatives passed a resolution to officially designate March 14 as Pi Day across the country. Here are a few business at which you can celebrate this mathematical day:
