HOUSTON (KTRK) --Today is March 14 or 3-1-4, otherwise known as National Pi Day!
We're not talking about pumpkin or pecan. Today is the day celebrating the mathematical constant of Pi that starts with 3.14.
What started as a nerdy celebration of the ratio of a circle's circumference to its diameter is now a day to get deals and even some free stuff!
Three Brothers Bakery in Houston is offering a free pecan pie to anyone able to show off their math skills.
