A flaw in a problem 2005-04-15

Bryce pose la question :
Question:

(x²-x²) = (x²-x²)
x(x-x) = (x+x)(x-x) [divide both sides by (x-x)]
x = x + x
x = 2x [divide both sides by x]
2 = x/x = 1

Where is the flaw in this problem?

Paul Betts lui répond.

1 + 1 = 1 2001-01-23

Stephanie pose la question :
My friend has this as a bonus question the other day and I want to figure it out. I don't know how 1+1 in any form could equal 1. Please let me know how you come about geting that.
Claude Tardif lui répond.
