I am currently hearing math at my university in germany and it is always difficult for me to translate the german topics into english.
We are talking about limits , sequences and series "quantities?", limes, triangle inequality , Cauchy etc. What subject would you guess am I hearing?
In germany we call this "analysis" but could it be possible that this is called precalculus in english?
http://www.khanacademy.org/math/precalculus/ At least those topics look familiar.
