Let + be a binary operation on a set G. + is commutative iff g + h = h + g for all g, h ∈ G. + is associative iff g + (h + k) = (g + h) + k for all g, h, k ∈ G. An element 0 of G is an identity element iff g + 0 = g, for all g ∈ G. For g ∈ G, a negative of g is an element − g of G, such that g + ( − g) = 0, where 0 ...
