Best ResponseYou've already chosen the best response.0i guess 4(m^2 + n^2 +m + n) always has to be even and even +2 remains the same ..

Best ResponseYou've already chosen the best response.14( n^2 + m^2+ m +n) +2, yeah this is enough to prove evenness.

Best ResponseYou've already chosen the best response.1I mean, it's a number divisible by 4 plus 2. I'm pretty convinced it's even, on a human level :)
