Q: You are a number-loving, research-churning, Euler-quoting mathematician. What will make your wardrobe complete?
A: The Number Crunch Long Sleeve Button-Down Shirt!
This 100% cotton shirt features symbols for addition, subtraction, multiplication, division, infinity, percentage, greater/less than, equal/not equal, and dessert. Um, we mean pi. It's both our favorite number AND dessert. Those two things might be correlated for a reason.
