Why can you pull out a scalar of a dot product, when it only applies to one vector?

Update:

For example,

(* is dot product, not multiplication here)

why does 2v * w = 2(v * w)

but 2v*2v does NOT = 2(v *v)

    The dot product involves multiplying two vectors together. The result is a single number.
