I wanting to do some papers at university, however I have long been out of high school and never really don math or science at high school. As an adult I am now keen to pursue some math papers and was wondering what kind of background I need. I have looked through various web pages and they refer to thing like pre-calc, AB calc, Algebra 1 and 2 etc. I am not in the US but believe these may give me good guidelines as to what I need to know to be able to handle math at university. I don't want to major , just want do some calc, stats, analysis and linear algebra stuff. I was wondering in what sequence do things like pre algebra , pre calc, Algebra 1 and etc go ?
