0:00 Kernel is a Normal Subgroup
5:20 First Isomorphism Theorem
The first isomorphism theorem is a fundamental theorem in group theory that gives us a powerful way to find isomorphic groups. In this video, we explain what the kernel of a homomorphism is and how to turn a homomorphism into an isomorphism!
