Each subgroup of 2: (operation +) is cyclic. Prove this by assuming that H is a subgroup
Chapter 15, Problem 15.29(choose chapter or problem)
Each subgroup of 2: (operation +) is cyclic. Prove this by assuming that H is a subgroup of2: and giving a reason for each of the following statements.(a) If IH I = 1, then H is cyclic.(b) If IHI > 1, then H contains a least positive element; call it b.(c) If a E H and a = bq + r, then r E H.(d) If a E H and a = bq + r, with 0::: r < b, then r = O.(e) H = (b).
