Turning in HW

I did a little extra as some personal practice...it should still work fine.
Without a Menu class: I would take the `options` and `translations` hashes outside of the method entirely. You can just put them at the very top of your code, and the methods will still have access to them. Then make separate methods called (for example) `operation_choice`, `get_user_input`, and `show_result`. 

With a Menu class: I would do the same things I wrote above, but inside the class. The hashes can go inside the class too. So you'd have (for example) `Menu.options`, `Menu.translations`, `Menu.operation_choice`, `Menu.get_user_input`, `Menu.show_result`. That's one reasonable way to do it.
