Brain Teaser of some sort.

For all you bored gimps , figure out whats wrong with this equation.

a² - a² = a² - a²

Correct ?
Alright now lets factorise abit, difference of two squares :

(a - a)(a + a) = a² - a²

Now lets take the common one out :

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

Following ? Mmk, now divide both sides by (a-a) to simplify the equation. [this will look ugly >.>]

(a - a)(a + a) = a(a-a)
___________ _____
(a - a) ------ (a - a) [Dashes in here are just to provide spacing btw, nerf FH]


We end up with this :

a + a = a

Then :

2a = a

2 = 1

Something must be wrong, now givf solutions =p.

___________ _____
(a - a) ------ (a - a)

Division by zero often leads to strange results. (a-a) always equals zero.

Correct ! Tbh I didnt expect such a fast answer...

For your sig, a = 0
