Can scalar multiplication be considered a bilinear transformation? Not talking about vector spaces etc. Just basic scalar 2 * 2 = 4. I can think of it as a linear operator 2 that takes one parameter 2 and returns 4. So it is a linear operation, is it not? But I can also think of * as a biliniear operator that takes 2 and 2 and spits out 4, right? Kind of like a mul(x,y) function in programming that takes two parameters and multiplies them and returns the result. Thoughts?
