    you have to get the absolute value sign alone first.

    @Markitos , solve the second part, and do take care of one thing that the expression which is in |dw:1359567749335:dw| sign becomes +ve when it is negative. this sign is called mod which converts -ve sign into +ve

    and how does the -1 become a positive one?

    because it is in mod sign , as i have already told that the expreesion in this mod sign becomes always +ve , if it is -ve

    no there is no 11, when LHS is not equal to RHS, then we put equal sign but we place a cross sign on that first write equal sign
