What is @balance?

@balance is never used in the video (https://teamtreehouse.com/library/ruby-foundations/ruby-core/enumerable), balance is the method which returns a sum of all the operations in the transactions array, but the @balance is still 0 at the end, why is it even included?

I am finding the same thing as well and would like to know why.

You are correct, it is not being used (so far as I can tell by skimming the vid). You could use @balance if you wanted to hold the current balance in a variable.

I should point out that while @balance and the method balance look alike (they have same name after all), they are in no way connected other than being part of the same class.
