I'm not sure what you mean. There are number patterns that are true for deeper reasons, but would also be 'just mathematics'. I more mean many number tricks don't really show an unusual fact about numbers, you're really just "dividing six by two" or similar.

Gridiron football, NFL etc orginated in Canada not America. At the McGill University in Montreal.
McGill took components of rugby and modified the rules, they introduced the concept of 'downs' .
In 1874 McGill travelled to Harvard to play the American version of football 'Boston Rules' which was more like soccer at the time.
The Yanks were impressed by the Canadians game and rewrote the rules of their own game. Switching to an oval ball and introducing downs and tackling.
Today the CFL in Canada continues to operate, with the Grey Cup being the oldest competition in gridiron. The rules of the two games still differ slightly.
