Granted, making your child wear this sweater to school will almost certainly result in his getting bullied -if not beaten up outright. Even so, it's still a pretty impressive design when it comes to working in math equations.
The main body of the sweater is a pattern of adding numbers in block shapes. There are also little x's in black. Circling the bottom in green on a dark blue background are Fibonacci numbers. Also circling the bottom and wrists in dark blue on periwinkle is the symbol pi.
Of course, if this sweater was sold in adult sizes, it could be a big seller in the Neatoshop.
