    Prove that the additive inverse -v of an element v in a vector space is unique.

    Yes, I concur. "A+y=A+z => y=z which is a contradiction" Is this correct? (u prolly noticed that I'm really weak in this, hence y I'm looking everywhere for answers.)

    Prove that the additive inverse -v of an element v in a vector space is unique.

    My bad. A and -A are elements in V and I am trying to prove that -A is unique. (basically replace A with v in the relevant equations.)

    Prove that the additive inverse -v of an element v in a vector space is unique.

    Homework Statement Prove that the additive inverse -v of an element v in a vector space is unique. Homework Equations Additive Inverse in V For each v in V, there is an element -v in V such that v + (-v) = 0. The Attempt at a Solution Assume that the additive inverse is not...
