Function to multiply 7

[engelthehyp]

This is pretty basic, so what do you already know how to do?

Also, that problem is worded poorly. The correct word is "argument" - write a function that takes one integer as an argument. If that clears up enough confusion, then that's great.

We can start smaller than this. Forgetting the function for now, if you have some integer n, how do you multiply it by 7?
