tv math gallery TV Math: 'Revolution,' 'The New Normal' and more fall showsEver feel like you’re watching the same shows over and over again? Blame TV Math. The suits at the networks want a sure thing, so they take part of one successful show, add a bit of another, subtract a plot point, divide by a character, and voila! All new television that isn’t new at all!

Sometimes the math works in a new show’s favor: the whole is greater than the sum of its parts. Other times, you get a mess of a show that makes algebra look like fun in comparison. 

Take a look at the equations that result in this season’s crop of shows … and place your bets on which ones will flunk out of class before the semester is even over.
