DOC: Minor typo in `Mutiplication` section

[afvincent]

I didn't find any function called prod() in itertools, so I assume that itertools.prod() in the documentation (section "Multiplication") refers in reality to itertools.product().

Besides is "outer product" the correct name for this product? In itertools.product() docstring, the name "Cartesian product" is used and Wikipedia doesn't seem to give the exact same definition for the two products (see Cartesian vs outer).

Yes, that should be itertools.product, can you put in a PR with that change?

Cartesian product is a bit more accurate (in that the result is the same dimensional), but not perfect in that the result is ordered (ex a[::-1]*b != a *b) where as sets are not.

It is more of a raveled version of of the outer product.

PR submitted.

I see your point on "outer product" rather than "Cartesian product", eventhough itertools.product is describded as "Cartesian product" in its own docstring, which forgets the fact it returns an ordered result (as it is also very common on the web to see questions and topics about the "Cartesian product of lists").
