    U = -20 v=0 a=2 t=10
    S = ut +0.5at^2. => -200 +100= -100m as total displacement
    S = vt +0.5at^2. => 0 +100m = 100m as total displacement

    Why does one give me negative answer and the other a positive?

     S = vt - \frac{1}{2}at^2

    Excuse me? It's -at^2

    Edit: [Sorry the Latex didn't load] So how am I using the equation wrong?

    Well in the OP you used the equation incorrectly as, S = vt +0.5at^2

    First time the page loaded the 'a' in your equation didn't load.
