OK, but this works only for a finite amount of numbers; now, there are infinitely many numbers from 1 to infinity.

But the correct answer is not infinity; it's a real number. And it's just astounding, I think.

This can not be defined because :

1. There's a contradiction: 0 divide by anything = 0 but anything divide by itself = 1;
2. You can't divide by 0

Good job.

Thanks Melody, MrGenius and MathsGod1;

There are two systems: The short system, or short scale, and the long system, or long scale.

In the short system:

1,000,000,000 is a billion

1,000,000,000,000 is a trillion,

1,000,000,000,000,000 is a quadrillion, et caetera...

In the long system:

1,000,000,000 is a thousand million or, more occasionally, a milliard (I love this word )

1,000,000,000,000 is a billion

1,000,000,000,000,000 is a thousand billion or a billiard

and so on.

The short system has always been used in USA; it was officially adopted by UK in 1974.

But the long system is still used in almost every non-English-speaking countries in the World.

To do arccos, click "2nd" then "cos".

"In that sentence, the number 0 appears 1 times, the number 1 appears 7, the number 2 appears 3 times, the number 3 appears 2 times, the number 4 appears 1 times, the number 5 appears 1 times, the number 6 appears 1 times, the number 7 appears 2 times, the number 8 appears 1 times, and the number 9 appears 1 times."

You're right, this was just a typo.

For the first solution: OK, that's a solution. But I think there are more than one way to do it; The solution I have is :

"In that sentence, the number 0 appears 1 times, the number 1 appears 7, the number 2 appears 3 times, the number 3 appears 2 times, the number 4 appears 1 times, the number 5 appears 1 times, the number 6 appears 2 times, the number 7 appears 2 times, the number 8 appears 1 times, and the number 9 appears 1 times."

If you think that all that calculation are wrong, then find a miscalculation.
