    Add the negative of z to both sides and use associativity of addition.

    Depends which ones. You can say things like "associativity of addition" etc.

    Re: Complex Number questions

    Ahh gotcha tbh I worked it out. Thanks for your help. The thing I don't understand still are partial orders and how u'd use it for a q like this. Also what the curved inequality signs mean.
