I think maths is relatively unique in that it is a really old subject that mostly doesn't depend on hardware. Sure computers have moved maths forward, but there's a lot you can do without. High school maths is pretty much Antiquity level, though much more formal. First couple of uni years are mostly 17-18th centuries maths. Last 2 undergraduate years is 19th and early 20th centuries. A few areas have changed though, particularly statistics I think, also computer science if you consider it part of mathematics, but have a look at a textbook from a 100 year ago, and you'll feel right at home except for the style.
