## Let's count to infinity!

### Let's count to infinity!

Yep, you read it correctly! This thread is now for counting to infinity.

Rules
1. You must count by 1's. No skipping ahead.
2. You may only count one number per post.
3. One person may not post two consecutive numbers.
4. No counting numbers twice!

Feel free to put whatever you want in your post , as long as the number is easy enough to spot. Feel free to be creative with how you express your numbers as well (no reason to be limited to basic decimal representations of numbers on a math forum!), but try not to make your representation of your number so abstract that others have difficulty determining what you meant.

Good luck to all of us. I really think we can make this happen.

Damn the rules, I was already planning to make a nice sum equation xD

You can post sums if you want; just make sure they're easy enough to understand. For example, I don't see anything wrong with posting an infinite geometric series. It probably wouldn't be a good idea to post an elliptic integral on the other hand.

$\lfloor\pi\rfloor$

$2+\Large\left\lceil\frac{13}{8}+\sum_{n=0}^{\infty}\frac{(-1)^{(n+1)}(2n+1)!}{(n+2)!n!4^{(2n+3)}}\right\rceil$

Some people should recognize the thing inside the ceiling

(I wouldn't have recognized that without the link...though I suppose the 13 and 8 should have been a bit of a clue :s)

$5_{12}$

Any other duodecimal fans here?

Also, would it be better if, instead of just saying not to put anything too complicated, I change the opening post to say to include the number in a spoiler if you suspect you might be using something others might have difficulty identifying or evaluating? I mean, in most cases, it shouldn't be bad, since you can just follow posts around it, but it doesn't (usually) hurt (too much) to be safe.

Clearly every even integer greater than 2 can be expressed as the sum of two primes.
I have discovered a truly wonderful proof of this proposition, but the signature is too small to contain it.

Let n be the number that is last posted. Then

$\sum_{k=0}^\infty(1-\frac{1}{n+1})^k$

So now we've counted up to infinity.

You may only count one number per post. It's in the rules, man

I won't get fancy, cause we need to get back on track here.
