I have to disagree here. In this particular case, where one performs basic arithmetic on just two variables, x and y are perfectly understandable. I would almost go sofar as to say that they are the most logical choice, given that many math texts use x and y, or x1 and x2, for bivariate functions.
i disagree with your disagreement, if someone was doing a very long program with much code then x and y would not be enough, it would make much more sense to declare the variable as what it actually is
