With the risk of looking like a complete fool, I have to ask this question.
In episode Dance Mania, Vanessa is trying to teach Cliff about the "new math" - something about some base method. I went to school during the 80's and I was taught the "old math" carrying the number and such when adding. A search for that "base method" in Wikipedia gives no results.
So my question is: Is that base method a real thing or something made up for the episode?
