Elementary question on multilinearity of differential forms

Question

Have I got this notion of multilinearity right? Say I feed $k$ vectors to a differential $k$-form and out pops a number, 3, for example. If I triple the size of one of the vectors, will the number then be 9? And so on, so halving one of the vectors would give 1.5. Is that correct?

Answer 1

That is indeed correct. There is little more to add to this answer due to the concise nature of the question!
