Me: What level of math?
Man: I want high math.
Man: No. I in Math 90 (at the community college). I go to Math 110. I need high math. I am good good good at math.
So, instead of naming off algebra, trig, geometry, precalculus, topology, abstract algebra, probability and statistics, etc., I take him to the section of math books and let him find his own "high math" book.
