Give an example of the associative property of vector addition using vectors in Cartesion form.
The Attempt at a Solution
I can't figure out how to get the arrow on top of my work so I wrote it without it.
I'm somewhat confused on why I am not getting the same answer for both like I should be. Did I make some stupid mistake in my work that I can't see, or does it have something to do with the coordinates that I chose to use?
u=(2,1), v=(3,2), w=(-2,1)
