In a more advanced sketch, we could imagine this ball and world having many more properties:

Both addition and subtraction with vectors follows the same algebraic rules as with real numbers.

The commutative rule: **u** + **v** = **v** + **u**

The associative rule: **u** + (**v** + **w**) = (**u** + **v**) + **w**

The fancy terminology and symbols aside, this is really quite a simple concept. We're just saying that common sense properties of addition apply with vectors as well.
