    ok so but tells you that there's 4 carbons

    the 1 bit tell you where the double bond is

    that's it

    so you draw a carbon with a double bond attached to another carbon then you draw the other 2 carbons in a row then fill in the spaces with hydrogen remember each carbon can make 4 bonds max

    No, that's the structural formula. The displayed formula is in the link Pigster gave.

    4 atoms in total 2 hydrogen and 2 oxygen
    multiply 4 by the constant and you get d

    That would be the structural formula, the displayed formula is basically the molecule drawn out like this
