Answer: We know that (Z, +) is a cyclic group generated by 1. As every subgroup of a cyclic group is also cyclic, we deduce that every subgroup of (Z, +) is cyclic, and they will be generated by different elements of Z. The cyclic subgroup generated by the integer m is (mZ, +), where … famous black astronomers
