Well its me init, I am a unix / C / C++ /Java / Perl / Stuff programmer. I code stuff to do stuff, that is about as specific as it gets.
The Piccy above is my son and I, the life in my life.
1) x = y 2) x^2 = xy (multiply both sides by x) 3) x^2 - y^2 = xy - y^2 (subtract y^2 from each side) 4) (x + y)(x - y) = y(x - y) (factor) 5) x + y = y (divide out (x - y)) 6) 2y = y (substitute y for x from #1) 7) 2 = 1 (What do you think of that?!)The mistake comes in step 5, when dividing by (x-y) on both sidesand the equation becomes (X+Y)* 0/0 = Y * (0/0) iff 0/0 == 1 then the result would be valid and 2 would in fact be equal to 1... this could make maths a little tricky.
