What is Normal Subgroups in Group Theory about?

The document provides proofs for 18 problems related to group theory. It begins by proving properties of subgroups, including that the product of two right cosets is a right coset if the subgroup is normal (problem 1), and that a subgroup of index 2 is normal (problem 2). It then proves that the intersection of subgroups and normal subgroups is also a subgroup (problems 4 and 5). The document also includes examples of non-normal subgroups.
