The applet shows how vector \vec{C}=\vec{A}+\vec{B} was calculated.
1. Calculate X,Y components of vector \vec{A},\vec{B},
  \vec{C}_x=\vec{A}_x+\vec{B}_x and \vec{C}_y=\vec{A}_y+\vec{B}_y
2. If you un-check x-y mode:
  The sum is equal to sum of parallel components of \vec{A},\vec{B} in the direction of vec{C},
  \vec{C}=\vec{A}_p +\vec{B}_p
  and the normal component of \vec{A},\vec{B} always cancel out with each other. i.e.
  \vec{A}_n+\vec{B}_n=0 or \vec{A}_n= -\vec{B}_n

You can select to operate in C=A+B , A=C-B or B=C-A mode.
