Dear all,
I've got Collell et al's book on microeconomic theory for first year undergrads. My maths is struggling to keep up with the Econ theory. In particular, where (in which book) can I learn the fundamentals of sets through which the chapter on consumer choice is presented.
A more general question would be: what maths do high school students study in the US before starting their first year Econ theory courses? I'd like to read up on that material too.
Grateful for any suggestions,
arn
