      Tell me what the symbol is for arithmetic sum?

      I know a geometric sum (factorial) is an explanation point, what's the symbol for an arithmetic sum?

      x??? = x + (x-1) + (x-2) + ... + 1

      I believe you are talking about upper-case sigma.

      Σ

      Although, I'm not entirely sure. I used that two years ago.

      Yes, Σ is right. So you'd represent x + (x-1) + (x-2) + ... + 1 as

      You merely have to change your point of view slightly, and then that glass will sparkle when it reflects the light.

      Hehe, sorry Howie. I was studying Maths a few minutes before I made that post, so it inspired me to do so.
