    You'll have to define what it is you are talking about.

    Are these the spreads?
    Are successive subtractions the spreads?
    Is each spread as important as any other?

    Mathematics is all about definitions. Generally, it is not safe to assume that everyone else knows what you are thinking. You must write it down.
