The subtraction of vectors A - B may be changed into an addition A + (- B). In the applet below A and B are drawn (draw button) first, then -B (in green) and then A + (- B) in red (subtract button).

If vectors A and B are given by their components as follows:
A = and B = , then the components of vector A - B are or
A - B =

Enter different components in the html5 applet below for vectors A and B and explain the results.
