# Sigma, Again.

#### TylaYuhh

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 ?

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.

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

#### TylaYuhh

Yes.

Oh, Okay. Thank you very much #### Plato

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.
