    hello there,
    Im taking a course at linear algebra and im searching for a list of the rules for sigma (I mean Σ the summation operator).

    google or wikipedia is always a good place to start when searching for this kind of thing.

    yes, I did, and then i found this forum....
    in wikipedia there's nothing that could help. google brings a lot of junk results, i guess sigma is a popular name..
    id be happy if u could help me with that.

    search for "summation" not "sigma." here is another link that may interest you. you might also like this

    also, you can do a search for "properties of summation" or something to that effect.

    the "identities" section of the wikipedia page i posted earlier should help you

    perhaps you could be more specific as to what rules/properties you are after...
