## 5/1 -- Intermediate: Problem solving session. (Oleg Gleizer)`We will go over the proof of commutativity of addition of non-negative integers one more time. Then we will proceed to solve problems from the next handout. If time permits, we will also discuss the solution of the functional equation xf(x+xy) = xf(x) + f(x` 2)f(y). The problem was brought about by Matthew Roth - thanks, Matt!## Handouts: |
