Re: Please Explain...

ZHero,

You haven't really shown that (N+2)^2 = 0, only that (N+2)^2 is divisible by 9.
Hence N must be one of 1,4,7 and you'll have to do something else to decide which.

I just did my calculation above and got (N+2)^2=0.
I mean, I don't Want to Show that (N+2)^2=0.
I just want to know what information does (N+2)^2=0 hold??

Re: Please Explain...

When you replace numbers by their digit sums and cast out nines you are essentially considering two numbers to be the same if they have the same remainder when divided by 9.


I would write
rather that
when I am doing this. Hence we have



We cannot now deduce that


since 0 has three square roots modulo 9. These are 0, 3 and 6 so we have


and since I'm biased against negative numbers
