ok, 1/3 + 2/3 = 3/3 or 1 correct?

But .333333333 (1/3) +. 666666666 (2/3)=.999999999 (3/3)

theoretically it should = 1

also
1/9= .11111
2/9= .22222
3/9= .33333        see the patern
8.9= .88888
so 9/9 should = .99999, but as we all know it = 1

math sucks

Well, that&#39;s why math seems to be so darn hard. Most of the stuffs people learn are thaught b4 college, and unless you are a math major in college, you don&#39;t get to learn why those things are true.

let me scratch it from back of my head.

ok.1/3+1/3+1/3 is 1. no question about it..if some one says differently, he&#39;s insane.

One of the most useful things that mathematics uses is called &#39;convergence&#39;. what this means is that when you have a sequence of numbers, then as the sequence grows to infinity, it will eventually converge(go close to) certain values within reasonable error that error will be reduced to 0 as the sequence grows to infinity.

Ofcourse, it&#39;s not for every sequence, but 1/3 problem is one that is solvable with convergence.

ok..we know that 1/3=0.33333333333333333333333333333333333333333333333333333333333333333333333 and it goes on and on, and 3 at the end will be present all the way to infinity.

well, here&#39;s the trick.

0.3 is 0+3/10
0.33 is 0+3/10+3/100
0.33 is 0+3/10+3/100+3/1000
and it goes on and on with terms that follow as 3/(10^infinity)

now, let&#39;s see this way. I&#39;m claming that 0.9999999....(sum of three 0.33......s)is 1.
well, let&#39;s see. 1-0.9 is 0.1
1-0.99 is 0.01
1-0.999 is 0.001

as you see, the difference between 1 and 0.999 gets to be smaller and smaller((3+3+3/10^infinity)). and as sequence of number (here. it&#39;s 0.999999....) grows, the difference will be so negligibel that in fact, it will be 1.

that&#39;s why they say that.

it&#39;s unfortunate that moving from rational numbers to real numbers, it gets screwed.. cuz rational number(1/3) is clean cut, but expression in decimal format will turn it into irrational number, the one with all the remaining 3s at the tail.

hope this helps

theoryically this may hard to believe but 1=2

I read like a 2 page formula to solve for that.
but you accually can make 1=2

nah...that&#39;s Homer Simpson&#39;s specialty....what&#39;s a fruitpastel?

I heard that there&#39;s this book called encyclopedia of mathematical symbols, and at the very end, they have proof of why 1+1=2 in mathemtical symbols, with no commom words. It takes about whole page, i heard.
