Let's celebrate Pi Day with a slice of pie

 

On March 14, math lovers from all walks of life around the world celebrate Pi Day, as a way to commemorate the mathematical sign pi.  The date written numerically as 3/14 match the first three digits of the never-ending number: 3.14 

This unique holiday is an annual opportunity for math teachers in schools across the country to talk about the infinite digits of Pi and for bakeries and grocery stores to sell pies at a discount for this day.
