Title: New Exercise: Plugging values into a formula and reading a table

I saw https://trello.com/card/board/plugging-in-x-and-y-values/4d87e664967a0775082939ab/4ea75825bddae015073db94b so I made an attempt at implementing it.

(As I read it this task was available, sorry if I misread and this was redundant.)
