We love us some math. (Or "maths" if you're from across the pond.) We can all agree on arithmetic, right? This is where we stash our products that feature equations, numbers, graphs, fractals, and all the bits that make math awesome. You need proof? (See what we did there?) We perform calculations and computations from algebra, geometry, calculus, and more on t-shirts, mugs, and assorted products for your amusement right here.
