    Sigma, Again.

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


    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.

    L-1 IS just one number.

    It's saying that the x counter goes

    1, 2, 3, \dots, L - 1, with 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 L-1 to a 4?

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

    Yes.

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

    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.

    If I didn't want your help, I wouldn't post for it.
    If I wanted your criticism, I would have asked for it.
    Please do not troll me for asking a question..which if i understand correctly, that is what these forums are for?
    And how exactly was I childish?
