Gauss' hemisphere
Gauss' hemisphere is another compactification of the plane R^2. The Riemann sphere is much better-known, and probably more useful, but Gauss' hemisphere is useful for studying some aspects of
projective geometry.
To perform the compactification, place a hemisphere on the plane, much like you'd place a... | {"url":"http://everything2.com/title/Gauss%2527+hemisphere","timestamp":"2014-04-16T16:20:12Z","content_type":null,"content_length":"21130","record_id":"<urn:uuid:2c76aa70-4eab-4c5e-8bf8-2545ff2ed2bb>","cc-path":"CC-MAIN-2014-15/segments/1397609538110.1/warc/CC-MAIN-20140416005218-00610-ip-10-147-4-33.ec2.internal.warc... |

Which is greater: 355*356 or 354*357?
Well, I'm looking through a means of solving problems and I just want a little more explanation to this method of solving that question.
Represent 354=a, 357=b, 355=c, and 356=d
