To get inside AVA, buzz Nile Geisinger at the door and I will come down and let you in. AVA has a nice chill room down stairs that we will be using.
Real analysis (traditionally, the theory of functions of a real variable) is a branch of mathematical analysis dealing with the real numbers and real-valued functions of a real variable. In particular, it deals with the analytic properties of real functions and sequences, including convergence and limits ofsequences of real numbers, the calculus of the real numbers, and continuity, smoothness and related properties of real-valued functions. - Wikipedia
