School subjects: Math

Hi, guys
The math teacher name is Pércio, he worked hard for this project. We like him, he's cool. Because of him we went to USP (the university of São Paulo) to the downhill.
In math we learned about a lot of things like: trapezium area, triangle area, circle and circumference, radius and diameter, pi and the construction of CARRINHO DE ROLIMÃ (It's similar to soapbox and billy cart).

Thank you so much, Pércio!
