# Prime proof q watch

Forgot to say that p cant be 3 and didnt bother with conclusion cuz I'm not sure if its correct

2. I think your proof is correct, but I feel that it can be improved a bit. Here's what I think:

- the fact that p, p+2 and p+4 are natural numbers is obvious, so you can delete the line about that
- add in the assumption that p > 3 from the beginning (so in particular none of the primes p, p+2 or p+4 are divisible by 3)
- you say "p+2 is a natural number" but then go on to study p+4. I think you meant "p+4 is a natural number" instead
- put the statement "p + 4 = 3k +l (for some integer k, and some l which is 0,1 or 2)" on its own line
- then you split the argument (as you've done) into the three cases: l=0, l=1 and l=2 to get the contradiction.

Summary: I think your proof is correct but personally it could be made clearer.
