I could find some uses for this too. Like halving your speeding fines.

a = b

a2 = ab

a2 - b2 = ab - b2

(a - b)(a + b) = b(a - b)

a + b = b

b + b = b

2b = b

2 = 1

Crikey dude, I haven't seen that stuff in years!!

Sorry dude, breaks down at the line "a+b=b"

Only holds true if a = b = 0, in which case the whole thing holds true right up to 1 = 2 which is once again a false conclusion. Sorry, but I'm an engineer and I can't leave this one opeg ;)

Algebra works, you can't beat it :done:

Yep, I'm with crashharry. Flawed conclusion.

It actually breaks down even before that.

At the line a2 - b2 = ab - b2
because a = b everything from here on is simply 0 = 0

Even if it were possible for it to hold true then it further breaks down at the transition from (a - b)(a + b) = b(a - b) to a + b = b , as the only way to make this step is divide BS by (a - b) which of course is dividing by 0.

A much simpler proof of how 1 = 2 is by definition:

Any number multiplied by 0 is equal to 0, or 0 x N = 0

N raised to the power of 0 is equal to 1, or N ^ 0 = 1

Now if N = 0 then 0 ^ 0 = both 0 and 1.

therefore 0 = 1 and by implication 1 = 2, 2 = 3 etc.

yeah....i'm with jantar on that one where it breaks down. :yes:

So what's a formulae where 2=1?? Could be handy to know for reducing speeding fines by half. Not that I think a judge would allow it but hey who knows. Proof is proof and mathamatical proof is the best proof.
