    by default when you want to subtract from a variable

    x=x-4;

    but in C we found that you can make
    x-=4;

    which is ofcourse easier

    for more simplification there is a way ONLY for incrementing to decrementing

    x++; //incrementing
    x--; for decrementing

    But as Walt and major said concerning subtractin more than one its prefered to make
    x-=4;
