amazing Proof

proofing that 1 = .9 repeating

1 = 1/3 + 1/3 + 1/3
1/3 = .3 repeating
.3 repeating + .3 repeating + .3 repeating = .9 repeating

therefore .9 repeating = 1

This was in the CB once....

But this is false.

.3 repeating is not equal to 1/3, it's just the closest thing we can get.

You can't have .9 repeating, as eventually truncation causes this to end. Infinity is not real, it's a human convention, thus .9 cannot repeat infinitely.

what about pie 3.14 and then aninfinite number huh ho do you explain that
and yes 1/3 = .3 repeating

Pie isn't a real number, it's a complex number. A less correct term that many teachers prefer to use would be "imaginary number."

right but get into advanved physics and calculus and then imaginary numbers become real

But the same rules do not apply.

1/3 is not .3 repeating. It is .3 repeating after being rounded.

no ive got four of my math teachers and a mathmatishen to agree wtih me

now if only i could spell

My math teachers think zero isn't odd or even as well... but that doesn't mean it isn't.

its not

It's even.

Mathematician.

0 is even. as it's a whole number multiple of 2.

a multiple of a number is a number that can be multiplied to equal that number



if you multiply 0 by anything you get 0


0 is not a multiple of 2







however 0 is even

SO MUCH MATH!! RAWRARARA!!!!! And yes, zero is even

what? 0 x 2 is 0. Thus 0 is a multiple of 2.

lol your right.... I was thinking factors

Well. If Odd and even number sequence between every 2 numbers than it must go -3,-2,-1,0,1,2,3.

How it works...


By the way, this comic is weird. On XKCD.com, the mouseover text reads "It's pi plus c, duh!"

But... that's not what it is. The integral of x squared is x to the third power divided by three, plus c...

You know, you probably could have made a better case for this, Kislany, if you showed up x/9 = .x repeating, so 1/9 is .1 repeating and 2/9 is .2 repeating and so on, and then said that 9/9 must then be .9 repeating, but is also 1. But, unfortunately (for you, at least), Civ and the others are right, .9 repeating != 1, because .9 repeating is not a rational number and thus cannot equal the rational number of 1.

And for our next trick, we shall prove that 2+2 can equal 3 or 5, depending on what the Party wants it to be.

1 = 1/3 + 1/3 + 1/3
1/3 = .3 repeating
.3 repeating + .3 repeating + .3 repeating = .9 repeating

therefore .9 repeating = 1

Yes, but .9 is rounded up to 1.

Zero is even, but people confuse even and odd with positive and negative. Zero is neither positive or negative, but it is even, not odd.

2+2=5 =D





for extremly large values of 2

Well... I talked to my math teacher about this today, as it was the second time I'd seen it, and told him why I didn't think it was true. He didn't sound entirely sure, but he said that he had some math book that had a section that had an algorithm that proved it and he was going to look for it. Should be interesting...

What kills me is that if 1=.9 repeating as shown with three thirds...

1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 6/3 = 2

.3(...) x 6 = 1.9(...)8

So does 2=1.9(...)8?

First of all.... zero is not a number, it is a concept for nothing in mathematical terms.

1/3 is most closely equal to .3 repeating infinitely
.3 Repeating Infinitely x 3 is .9 repeating infinitely.

the problem is that 1/3 cannot be turned into decimal form. The system of numbers works on a scale of ten. 3 is not a factor of ten, 100, 1000, etc. so it can never perfectly exist in it.
