The average person may just think today is March 3rd. But to numbers nerds and math teachers, it’s much more than that. Today’s date, 3/3/09, is a square root. √9 = 3, or 3² = 3 × 3 = 9. For the math impaired, 3 is the square root of 9.
Square Root Days, as they are commonly called, only occur 9 times each century. If you weren’t paying attention, then you might have missed the last Square Root Day on Feb. 2, 2004 (Groundhog Day). So enjoy today while you can. Go take an extra quiz or study for the SAT or GRE. The next Square Root Day isn’t until April 4, 2016.
