    well that just confused me
    Let's say you what to find the sum of the integers between and including 1 and 10 i.e. 1+2+3+...+10, this can be written as \displaystyle \sum_{r=1}^{10} r. There is a formula for computing this and other common sums.

    It's a basic example but I've seen more complicated usages such as where it intersects with integration and it makes my head spin.

    See this: http://www.mathcentre.ac.uk/resource...ntre/sigma.pdf.

    It's a general term of the sequence. If I were adding square numbers, 1^2 +2^2 +3^2 etc, then I'd have written r^2 instead.

    Maths. I can do the basics perfectly but anything beyond that is hard for me. I struggled with art because I can barely draw a stick man, let alone paint a masterpiece. I excelled in every other subject though pretty much.

    Yeah I think that's why the clients can afford to give away such things!

    She isn't rich or anything though :rofl: Actually her mom was very poor and emigrated from India :O
