Ooo here is what i posted earlier.
But the LaTex Post didnt help me :/.


\(\displaystyle floor(\sum_{x = 1}^{L - 1} floor(x+300*2^x/7)/4)\)

Im not looking for free answers...Just help on this formula :)

I understand Sigma but not the part on top of it, the 'L-1', Usually it is just one number?

Maybe someone here can walk me through it :D?

Please & thank you :) in advanced.

Why should we have to go to a link for your problem?
Why can't you type it here?
You have been given the LaTeX link.

\(\displaystyle L-1\) IS just one number.

It's saying that the \(\displaystyle x\) counter goes

\(\displaystyle 1, 2, 3, \dots, L - 1\), with \(\displaystyle L\) being the "level you're calculating for".

Do you really think i would waste my time registering a account ( not to mention with an email address that contains my FULL name it in? ) just so someone will go to a link?
What do you think It would be a virus? Which you can't even get UNLESS you actually download it??

How can people go on a math help forum if the 1st time they post a problem (second for me because first time was correct, but not a help on the part i am stuck in.) they get mad...and say "Why should we have to go to a link for your problem."
...
I am looking for help, not accusations. I didn't type it because I do not know how to type the capital sigma sign.

Lets say L was equal to 5.

Would that just mean you can replace the \(\displaystyle L-1\) to a 4?

\sum_{x = 1}^{L - 1} gives \(\displaystyle \sum_{x = 1}^{L - 1}\).

Yes.

Though I would say that in your code, you would specify what \(\displaystyle L\) is somewhere before your sum, not actually inside it.

Thank you :) I will post the problem. Did i post it correctly? I don't know how to make the /4 under all of it :/

I apologize for..acting rude at 1st.

You can learn to post with LaTeX.
If you don't want to, why should we help?
BTW: You response to me is really childish.
