# Another integers mod 4 question

Use the first isomorphism theorem to show the following:

Z/(4Z) is isomorphic to Z4.

There are other ones to solve I'm just using this as an example so I can figure out the thinking behind it. I can prove it with multiplication tables, but in reference to the F.I.T. I'm not sure how to start.

What is Z4? Do you mean C4 (the cyclic group of 4 elements)

What is the first isomorphism theorem?
