Section 2.2 says:
By convention, a^0 is equal to the identity element for any a in G.
It should say:
By convention, a^0 is equal to the identity element and a^1 is equal to a itself for any a in G.
Without this convention the explanation on the next page: "... for any integers X and Y: a^(X+Y) = (a^X)*(a^Y) ..." would be incomplete, as being undefined for the integers X=1 and/or Y=1.
