Have something about math you want to share? (challenge, problem, paradox, etc...) Post here.

[b]A math paradox:[b]

0x1=1
0x2=2

Therefore:

0x1=0x2

Dividing by zero gives:

0/0x1=0/0x2

Simplified:

1=2

Espen, what crack are you on? Poor guy mustn't have passed second grade... (or at least that's when I learned basic multiplication)

... What?

0 multiplied by anything is 0.

Several years ago I discovered that there is a relation between the number 6 and multiplication with any number. This is a great help to anybody who doesn't have a calculator, or cannot multiply at all.
If you multiply a number by 6, and seperate the digits of your answer into columns, ones and tens, the digit in the tens column will be half of the digit in the ones column.
e.g, 6 x 8 = 48
|tens|ones|
| 4   |  8   |
6 x 6 = 36 | 3 | 6 |
6 x 4 = 24 | 2 | 4 |

(sorry for the terrible diagrams)

So to get the answer of 6 multiplied by X, halve X and stick your answer in front of X.

It gets more complicated for odd numbers and multiple digit numbers.
For odd numbers, you will get X.5. Stick the 5 in the ones column, and then add it to your original number.
e.g.,6 x 3 = 18
|tens|ones|
|1.5  | 3   |
|  1  |  8   |
6 x 9 = 54 | 4.5 | 9 |
|  4  |  14  |
|  5  |  4   |
(If you get a two digit number in the ones column, move the first digit to the tens column and add it to whatever number that you've got there already)

For multi-digit numbers, you will get two digits in the ones column. Move the first digit to the tens column and add it to the number that you have there already.
e.g.,6 x 10 = 60
|tens|ones|
| 5   | 10  |
| 6   |  0  |
6 x 30 = 180 |hundreds|tens|ones|
|    0      | 15 |  30 |
|    1      |  5  |  30 |
|    1      |  8  |   0  |
It's complicated, I know.
I was seven when I figured this out.

Stupidest shit I ever saw. And I thought Swedish maths ed. was bad.

And Caboose's post:
0.999 x 10 isn't 9.999, it's 9.99.
So 10c - 0.999 = 0.891. Fail, seriously, why must you ALL FAIL?

Here's maths for you.

Ok.. you all fail at writing Math in forums.
0x1=1
0x2=2
I'm confused by this...I'm sure you meant "zero To the power of one". and "zero to the power of two" ???? Maybe not? 0? ???
Either way what you do next is stupid (divide by zero? go away.)

@TJB:

Please use either images, or the [PRE] Tags.

0.999 x 10 isn't 9.999, it's 9.99.
That IS true, BUT: in the original post it's 0.999... x 10 meaning that it's .9999 recurring, ie: the .999999999999999999 continues on ad infinitum.
That ... really should be a single superscript dot in proper notation i think.

Oh right, didn't think of that. In any case, this 0.999... = 1 debate is stupid.
Posted 12 years ago2007-06-13 12:45:57 UTC Post #225104
Yeah.. and also: i think someone should make "Division by zero" a bannable offence on the forums. :x

<Caboobs> 0x1 technically means 1 hex.
<Caboobs> In which case 0x1 = 1 is correct.

Yes.. if it's hex it's right. But the devide by zero bit is still wrong.
Posted 12 years ago2007-06-13 13:00:30 UTC Post #225110
I think he meant:
0 * 1 = 0
0 * 2 = 0

0 * 1 = 0 * 2

Divide each side by zero (!?!?!?!?)...

1 = 2
Which I'd say is right.
Posted 12 years ago2007-06-13 13:05:43 UTC Post #225111
Still, DIVIDING BY ZERO Cannot be done. Reason it out. How can you divide something into no parts? nothingness??

Spelling error. There you have it. It was supposed to be

0x2=0

(x * y) / x always equals y. It doesn't matter what x or y may be.

That doesn't make any sense, splint.

Nothing in your equations shows 1 being infinity.

What do you base this on?

Formula which will in theory equal infinity:

lim y>0+ x/y = +∞

You divide by zero to eliminate the [pre]0 * x
So it actually goes like this:
0 * 1 = 0
0 * 2 = 0

Therefore:

0 * 1 = 0 * 2

Divide by zero: (to remove the "0 * x")

0 / 0 * 1 = 0 / 0 * 2

1 = 2
There. I finally got it right.

You still can't divide by zero.

You're still trying to divide by zero.

Posted 12 years ago2007-06-13 18:26:29 UTC Post #225159
Zero isn't anything. Zero = nothing.

Dividing by zero is like seeing how much of nothing is in a number. It's not at all.

Oh FFS.... Espen, PLEASE, try and understand!

0 x 1 = 0

0 x 2 = 0

You ok so far.... not going too fast?

(0 x 1) = (0 x 2)

Ill let you have that one, as you're stating 0 = 0, which is correct

So, it 0 = 0 then you are attempting

0/0 = 0/0 ........which means both sides equal zero.

0 = 0 .........OMG, COOL MATH!!! :roll:

Posted 12 years ago2007-06-13 19:37:24 UTC Post #225164
YOU CANT DIVIDE ZERO BY ZERO. try it on a calculator. it'll spit out an error.

lets do this:
0 * 1 = 0
0 * 2 = 0
Therefore:
0 * 1 = 0 * 2

0 / 0 * 1 = 0 / 0 * 2

NaN * 1 = NaN * 2
There has been a break in Operation - Reason: Cannot multiply an integer by a null value.

n / 0 = infinity. Thats why.

So:

1 / 0 = infinity

2 / 0 = infinity

( 1 / 0 ) = ( 2 / 0 ) True.

Windows Calculator spits out a "Undefined Result" here's why.

Think in terms of graphing. You can have a slope of 0/1 which is a horizontal line. However, when you have a slope of 1/0 it is properly called an undefined slope. A perfectly vertical line doesn't have any slope. The line's rise is infinity and its run is still 0.

Calculators can't do infinity.
