# Math Help - I need some pratice with equations and formulas.

1. ## I need some pratice with equations and formulas.

So, Im in a school where we do ALOT of electricity math, and it is basiclly focused on re-writing formulas, like $U = I * R = I = U / R$. That ofcourse is very basic, but im looking to get som pratice on that subject. Anyone here with ideas on where I can get me pratice?
