Subject: query

Let a = 4000, b = 2000 and c = 6000 > a + b =c Multiply both sides by a + b > (a + b) (a + b) = c (a + b) > a*a + ab + ba + b*b = ca + cb > a*a + ab - ca = cb - b*b - ba > a( a + b -c) = -b(-c + b + a) > > so > > a = -b > a + b =0 ............... Where is the violation of mathematics rule..pls suggest. --pankaj
