Pascal's Triangle and Its Relatives

Background

Here is the simplest example of Pascal's triangle.
Why should we care about this arrangement of numbers?
How is this related to fractals?
We generalize the even-odd distinction using modular arithmetic.
What happens to Pascal's triangle mod 3?
To look at more general versions of Pascal's triangle, we take a brief excursion into some group theory.
Other questions we can ask about Pascal's triangle.
