• -2, 2 are swapped in vector length labels
• -v should be labeled in last diagram

This is fixed in the original illustrator file, but has not been exported to new PNGs (waiting until we sort out build and directory paths.)

@jasongao97 this would be a good issue to test the new workflow of fixing an image in notion and having it populate to the github repo? Or am I supposed to upload the image to the repo and then update it in Notion? I don't remember!

@zee-em I noticed we lost the 2 and -2 labels on the far right vector? I think those are helpful to include.

I'm also now wondering if we should show a light grey vector as the result of the subtraction (see red one above) and even if the dotted lines in that 3rd diagram should be removed?

note: change dotted lines to gray rather than remove

[shiffman]

also switch the -2 and 2 dotted lines to the other side of the arrow on the far right
