This was absolutely perfect. After going through quite a few different sources for explainations, this, by far, was the clearest and easiest explaination to help me understand. Thank you for this video.

So glad to have stumbled across this video. I couldn't understand what my books were saying and in less than 8 minutes you've cleared up all the confusion.

Thank you for your very clear explanation. I will be working my way through your other videos!

regarding no. 5

if n is anything other than a prime, is there even a primitive element?
Since the totient(n) will be less than n-1 even if an element had this order it wouldn't generate all the elements (since there are still n-1 elements).

Is this correct or am I missing something?
Great videos dude.

So, primitive element is the element that has to go through all elements before it reaches the identity element that is 1?
