Section 9.2: Analysis

In this section Hungerford classifies all Finite Abelian Groups. The first section that may cause some confusion is in Theorem 7.9 where he suddenly calls upon k without previously defining it.  It seems that k may be the the number such that a^k =e (in the multiplicative notation) or ka=e (in the additive notation).

The Fundamental Theorem of Finite Abelian Groups seems to be very important but Hungerford doesn’t explain, or provide more than one example detailing, what it means.
