Mozart piano Sonata no 9 and Beethoven Sonata no 13?

I'm uming it's Beethoven Op. 13 and Mozart K.310. The Beethoven is No. 8 in my book too, and the Mozart is No. 9 in one edition I have, but those numbers are kind of arbitrary. I don't know what you are even looking for for an answer. They're both in sonata form (duh). I find many more differences than similarities.
