People who love numbers and/or Math can be unfairly labeled as nerds, geeks, or even dull folks. This is so not the case! Take, for instance, the term Pi, also known and Archimedes constant. In basic mathematics, Pi is used to find the area and circumference of a circle. It starts as 3.14 but technically goes on forever after that since it is an Irrational number! KA-BOOM! Your mind is blown, and you know it! This is a great shirt to celebrate your love of math and numbers or Pi day. The shirt is a soft style ring spun fabric blend of 90% cotton /10% polyester. Makes a great math teacher's shirt.
