    -Difference Equations
    -Permutations and combinations

    I am just new to teaching Math and I want to be able to make the class as interesting as possible!

    Just a small example. In the Premier League in England, there are 20 clubs. You can calculate the number of matches using formula: N=n!/(n-2)! where n= number of teams, 2 is the number of teams in one match.
    With that data you have N=380 (matches).
