This applet visualizes addition, substraction and scalar multiplication of vectors.

Draw two vectors on *XY* plane by left mouseclick inside the marked
internal square. You can drag those vectors around with your left mouse pressed
before
you find the appropriate position for them. After two vectors are drawn, you can
you can still relocate them by clicking on vector arrow and dragging it to a new
location.

Press one of the functional buttons on the left to build vector sum
** 'A + B'**,
find difference **'A - B'** or** 'B - A'** or to calculate scalar product of two vectors.
Once the resulting vector is built, you can drag the whole vector structure by
grabbing the arrow of one of the initial vectors components.
While you drag, the vector attributes are dynamically recalculated and redrawn i
n
the corresponding report window on the right.

You can go one step back in you vector drawing by erasing your previous step or
you can erase
everything on the* XY* plane and start all over.

Button "Help" opens Help window.
