1 = 2

Lord Kagan · 31 Aug 2006, 22:10

let a = b

a² = ab

a² + a² - 2ab = ab + a² - 2ab

2(a² - ab) = a² - ab

2 = 1

Multiply both sides by a,
Add (a² - 2ab) to both sides,
Factor the left, and collect like terms on the right,
Divide both sides by (a² - ab)

tell me if it makes sense

2(a² - ab) = a² - ab

is correct cause 0=0

but not 2=1

at least this is what I remember from math...but that was long ago and it was far away...oh god, how very far...

I don't understand how you came up with 2=1???

Lord Kagan · 31 Aug 2006, 22:37

im a math "genius"

you get it because you times the first brackets by the 2 while the second side after the = isnt multiplied by 2

mszee · 31 Aug 2006, 22:40

2 multiplied by 0 is still 0????

Then yes...it's not 2=1 it's 0=0

You MUST be a genius...

Lord Kagan · 31 Aug 2006, 22:42

I dont get 0 from that line though

Lord Kagan · 31 Aug 2006, 22:43

Did you work it out by cancelling out the same numbers/letters?

Chris · 31 Aug 2006, 22:57

2(a² - ab) = a² - ab

You should get 0 from this line.

You stated a = b so if we subsitute we get 2(a² - aa) = a² - aa

Apply the basic rule of calculus that brackets, division, multiplication, ddition & subtraction must be done in that order and we get:

2(0) = 0

Thank god I am not senile yet!!!

What??? What did you just say??? I didn't get it...

Lord Kagan · 01 Sep 2006, 18:49

Ill never say it again

mszee · 01 Sep 2006, 19:05

No, I seriously just didn't understand what you've said...

Lord Kagan · 01 Sep 2006, 19:06

the way i worked it out i got 2 instead of your anwser of 0

mszee · 01 Sep 2006, 19:06

Don't worry...my first answer was wrong too...hahahahahaha...I was just quick enough to delete it...

How about this one then:

The square root of 25 (sqrt(25)) is +/- 5

So,
sqrt(25) = sqrt(25)
5 = -5
10 = 0 (adding 5 to both sides)
1 = 0 (dividing both sizes by 10)

We know that for all numbers A, A*1 = A
Also, we know that for all numbers A, A*0 = 0

So, if we multiply both sides of that last equation by A, we get:

A = 0

Thus proving that all numbers equal zero.
