Am I going crazy or is 2 = 1 ?

Let a = b

a = b

a^2 = ab

a^2 - b^2 = ab - b^2

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

a + b = b

a + a = a

2a = a

2 = 1

Wtf?! :eek:

is funny what u posted, but that rationament sneaks two basic rules of mathematics:

  1. any multiply of 0 would be everytime 0 so (a+b)(a-b)=0=0*anything else.

  2. any number divided by 0 would give infinite, so in (a + b)(a - b) = b(a - b), reducting the egality with a-b would mean dividing to 0, so infinite=infinite

but funny :slight_smile:

[QUOTE=maniac]

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

a + b = b

Your mistake is right there, you can’t divide by zero

you evil bastards! didnt even give it a day! :smiley:

lololol i hate math but there right :slight_smile: lol i am in math105 in college and damn its been awhile :stuck_out_tongue: but i still kinda know it :stuck_out_tongue: lol

here is one for you:

0.999~ = 1

With Algebra:

[PHP]

x = 0.999~

    10x = 9.999~ 
10x - x = 9.999~ - 0.999~ 
     9x = 9 
      x = 1

[/PHP]

EDIT: Cleaned it up a bit and added formatting to make it easier to read :slight_smile:

– OR –

With Fractions:

1/9 = 0.111~
2/9 = 0.222~
…
7/9 = 0.777~
8/9 = 0.888~

Following that line of thought, then 9/9 = 0.999~, however, dividing a number by itself always equals 1. So therefore 0.999~ = 1.

Rattle that around in your brain a bit =)

You people are evil :mad:

Oh and there is no invinity, no matter what anyone says - so 1/9 isn’t 0,111~ but 0,111~112

And 9,9999~ + ~0,0001 = 10/10=1 :dunce:

No… just leaving out a significant figure.

[PHP]

x = 0.999~

    10x = 9.999~ 
10x - x = 9.999~ - 0.9999~ 
     9x = 8.9991
      x = .9999

[/PHP]

No matter how long it goes on for, 10x - x will end with a 9. ie 9.000…9

Yes, but then the question is: How long before you get to the ~112 ? :smiley:

So there can be an infinity because nobody knows exactly how long it will go until you reach that ~112 :wink:

It’s at the end you silly :tongue2:

Crap. Now my brain hurts.

:bomb:

1+1=2

I have always fuckin hated the math, but its the truth :kos:

If 0 divided by 0 is defined, then 2 = 1.

Anyhow we all know that:
00 = 0
0
1 = 0
10 = 0
1
1 = 1
and
0+0 = 0
0+1 = 1
1+0 = 1
1+1 = 1
…right? (Seriously ;))

yes, you are correct, but how long before we get TO the end? Nobody knows…

Its one of those “Questions of the universe that we will never know.” :dunce:
