Ruby programming language

Is there a way where I could access a hash from one method in another method? In this case, I'm trying to access the 'hash' hash from the 'add' method in the 'entries' method. That is where I want the entries method to display whatever hash (from the add method) has inside of it.

PS: If you have the time, please explain why the program displays numbers when I ask it to display the 'entries' method
