You really don't need a book in any language to learn math... numbers look the same in all languages :)
If you really need theory to understand it try to search something on the Internet, it's the easiest solution and time-saving.
Good luck, I've already forgot all of it, but it wasn't so bad after all.
yeah you know. i do this. but sometimes they are teaching something in polish, they say something, and there's nothing like that in English with google translator!! and it's hard to find out what they are talking about :(. so i end up not knowing. i know math is the same everywhere.
in my lectures, sometimes they say somethings that i can't find English translation for. and it's hard to find what they are talking about.
