I thought of a way to use Gaussian integers to show that NxN~N(adsbygoogle = window.adsbygoogle || []).push({});

We look at (1+i)(1-i) and this corresponds to the coordinate (1,1)

then (1+2i)(1-2i)-->(1,2) then (1+3i)(1-3i)-->(1,3).... and you keep doing this, so we have injected NxN into N.

Have something to add?
