The rule named for this mathematician adds  two combinations together to equal a third combination: the two original combinations have the same   first number, which is one fewer than the first number in the third combination.
This mathematician improved Pierre de Fermat's solution to the problem of points, which determines   how to decide a bet when a game cannot be completed.
