Christmas may be the most wonderful time of the year, but we'll call Pi Day a close second. This semi-official day celebrates the mathematical constant of pi, or the ratio of a circle's circumference to its diameter. Because pi is approximately equal to 3.14 (continuing on for about a trillion digits), March 14 (3/14) is set aside as the day we gather together and celebrate the wonders of mathematics. Oh, and eat a lot of pie (hooray for homophones!). As our personal contribution to this glorious holiday, we're giving you a numerical cheat sheet for all things personal finance. Enjoy, whiz kids!
