I am a graduate student studying mathematics. Specifically, I study mathematical logic. I have interests ranging from recreational to more serious in many areas of math and logic, including type theory, lambda calculus, recursion theory, set theory, topology, algebra, and combinatorics. I've tutored math for almost 4 years, and am presently a TA. I try to answer questions concisely. I fail often I'm sure. I apologize if I'm not clear. I keep track of the more advanced questions I answer for edits by the poster, so please let me know if I didn't make myself clear. You can email me if you have any specific questions.
