Great teaser. tsimkin Apr 15, 2005 If we can live in a world where 2=6, then why should we assume that the transitive properties of an equal sign hold? beethovenswig Apr 15, 2005 I can not believe I fell for it!! I thought 5=9. Great teser bobthesnail Apr 15, 2005 Modulo 4 arithmetic means that you always divide the answer by 4 and only care about the remainder. So 3 (mod 4) + 3 (mod 4) = 6 (mod 4), which equals 2 (mod 4). Often used in data coding. Also quite common in programming. FeaerFactorY666 Apr 15, 2005 Great!
