I'm trying to understand imaginary quadratic fields and the ideal class group seems to be really important, yet I cannot find a simple explanation of it and why it's important. I understand that it is related to unique factorization, yet I don't know why. If someone could give a simple explanation of it and maybe a simple example of it I'd really appreciate it.
