Walker never pointed out that w+1 is divisible by w+1 and divisible by 1, and since none of the primes divides into w+1, that w+1 is necessarily a new prime. Hence there is no contradiction to 2) and hence no proof. So until L. Walker admits his mistake of approving a fake-proof, we are just going to see more rudeness and a deterioration of math posting from the UK. Usually the people of UK are overly polite and deem our praise on their politeness, but I guess every barrel has its rotten apple.

Every natural n is divisible by n and by 1 n = 1*n Has it taken you 20 plus years to work out what most children know by 10 ? "one times n is n" "n over n is one" Can you actually "do sums" at the level of a six year old ? |
