    Subtracting vectors?

    Hello there! I'm in some urgent need of some help to subtract vectors.

    I can't seem to find out how to subtract them, I checked the sparknotes help page, SparkNotes: SAT Physics: Vector Subtraction and tried it out with a question, but i can't seem to be getting the right answer.

    And I've also been told of a tail-to-tail method approach which i don't seem to understand as well. If anyone has any decent sites / explanations they can provide, it would be great.

    If you are interested in the question it's PQRS is a rectangle and PQ - RQ = PS - RS (all sides are vectors). Thank you!!

    This may help

    Note that -RS=+SR and -RQ = +QR (why?)

    When you add they are both the diagonal of the rectangle.

    Good luck.

    P.S Cool name
