Hippotenuse — The Cute Maths Geek T-Shirt
Show off your inner geometry geek (and your excellent taste in puns) with our Hippotenuse tee. A cheerful hippo in full professor regalia struts confidently across the chest, declaring that being “sqrt(hippo² + tenuse²) = awesome” is the only theorem that matters. It’s the perfect conversation-starter for study group, maths club, or laid-back weekends when you want your humour as crisp as your angles.
Why you’ll love it
-
Maths-class meets streetwear – playful graphic that only the initiated will fully get.
-
Soft, breathable cotton knit – comfy enough for marathon revision sessions or all-night coding sprints.
-
Unisex regular cut – neither boxy nor clingy; sits just right on every body type.
-
Colour-fast print – bright pigments that stay sharp wash after wash.
