Vector addition/subt?

When im looking at vectors, is there a difference in saying x-y , or y-x , does that matter in terms of vectors? since subtraction of vectors mainly includes two vectors that travel in opposite directions

    yes because your minus and positive either attracts or repels one or another.

    Yes. Because sign (direction) matters

    X = + 5

    Y = - 5

    X - Y = 5 - (-5) = 5 + 5 = 10

    Y - X = - 5 - (+5) = - 5 - 5 = - 10

    Not the same
