Title: A funny little problem, can anyone solve it?
Post by: Bossieman on September 18, 2001, 08:44:41 AM

I will prove that 3.999999999999........=4

X=3.999999999999...........

10X=39.99999999999999999..........

9X=39.999999999999..........-3.9999999999999999999

9X= 36

X= 36/9
X=4

So 3.9999999.......=4

Is there something fishy here?

Oh I\'ve got a solution...

3.9 repeating DOES not = 4

It does =4 there are certain analogies you can use to reach a theological conclusion

For example..  Standing on some train tracks and a train is comming at you.. You know that if you don\'t move its going to hit you... Yet mathamaticaly speaking the train will never hit you..

its 2 feet away, then its 1 foot, then a half .5 , then .1, then .11111111 , then .011111111

But you know it will reach 0...  At which point you are squished..  So   3.99999 does = 4 once you reach the matter of threshold...

3.999999999999999999999..... is not 4.

Trust me on this one, ok?

3.9999999999999... can be expressed as
lim______4 - ( 10 ^ ( -n ) )
_n->oo

The value of the limit is 4. For any writable portion of 3.9999999999999..., n would be an integer.

Okay, I think I remember now, I believe you can\'t do step 3;

9x = 39.9999999....   -  3.9999999

because the 3.99999 goes to infinity and there are special rules to handle numbers that go to infinity because they\'re not really numbers (bear with me).

well yea its step three because if you think about it

the 10x is possible by just moving the decimal over one but you cant do that with the 9x - you have to times the last digit by nine which isnt possible - also if it was the last digit would be an 1 - 9x9=8\'1\' which would not make it and even subtraction

so there :P

No more maths.

Not even the wise old Yoda could this solve...

3.9999999999...... does indeed equal 4 because once you get past the 10th 9 the resulting actual difference between 3.9999999999..... and 4 is so small that for any practical applications you should just say "Fukk it, it\'s good enough". Nobody likes a nitpicker. :D

1+1 isnt really 2.. Its 11..
See put 1 next to 1 and it makes 11!

Just like 123+456=123456

EASY!

1+1 = 3
