Hash iteration keys : I have this hash:

       games = {"Mario" => "SNES", "Ico" => "PS2", "Tetris" => "Gameboy"}

I want to make a method that will convert the keys to integers and then add  all of the keys in the hash together and return a single integer

I looked up some methods on rubydocs and came across the string method .ord which converts letters to their numerical values.
I know I will want to split('') the keys I'm just not sure how to get it all to work.
