Why wear your personality when you can add it up?
This shirt isn't just soft and stylish—it's mathematically clever, emotionally nostalgic, mildly sarcastic, and dangerously punny. In other words, it's everything you've ever loved... or tolerated.
Perfect for the person who’s been told “you’re a lot”—because now you can prove it with math. Whether you’re a dad-joke dealer, a retro junkie, or just someone who peeks at the answer in the back of the book, this shirt solves the equation of: YOU.
SUM SHIRTS: Because basic math = obviously awesome.
