I need help in high school physics?
How do you add and subtract vectors.
Also how do you multiply and divide. Some websites would be nice.

draw a diagram, and draw the vectors in arrow form (according to direction and magnitude). connect the arrows – the 1st one’s arrowhead to the next one’s line. then make a line from the origin to the 2nd vector’s arrowhead and there you have your new vector.
to be more exact, get the x & y coordinates of the vectors first (sohcahtoa), then add accordingly: x1 + x2, y1 + y2. use the pythagorean theorem to get a new magnitude from the new x & y.
