The origin is `(0, 0)`. The origin is `(0, 0)`.
`add` and `mult` can take vectors as well as numbers. Many math functions take vectors as well as numbers, e.g., `add` and `mult`.
You will see vectors indicated in patterns by an `(x, y)` tuple.
You can see what this looks like in the last clause of `add`: `((x1, y1), (x2, y2))`.
