About this collection

Times Table Champion and Human Calculator are for the confident ones, Numbers Are My Thing and My Favourite Number 7 are gentle, and Maths Arcade, Maths Speedrun and I Came For The Pi suit kids who like a joke with their sums. Every design comes as a T-shirt for £4.99 or a hoodie for £9.99, so you get a proper top that can be worn again rather than a costume that lasts one morning.

Unisex kids sizes 3-4 to 12-13 years. T-shirts in Black, White, Red, Green, Blue and Heather Grey; hoodies in Black, Heather Grey, Navy, Pink, Red and Royal Blue. Each one is printed to order in the UK using vinyl transfer. UK delivery is £4.99 standard or £6.99 express, and free when you spend over £50.
