It's quite possible that Gauss figured that out when he was young. I actually figured it out when I was 8. Being a young, anti-social kid, I tried adding numbers between 1 and as high as I could go, trying to find a pattern. The funny part was that I didn't know what variables were, although I did know fractions. My formula was something like, "Take a number, add one, divide by two, and then multiply it by half of the original number." It seemed very strange to me that that formula seemed to hold for any number I gave it. One day I even added all the numbers up to 20 in my hand to see if I got 210.

Anyway, one day I told my math teacher that I figured out this neat formula and then she introduced me to concepts like "variables" and "functions". :)

    Gauss did indeed figure this out at the age of 8 .. a teacher had given her unruly class the "busywork" problem of summing the first 100 integers. Gauss is also notorious for catching errors in his father's bookkeeping at an even earlier age. This from A Biography of Gauss

[james28909]: i figured it out
[james28909]: upon trying various solutions, i was forgetting to package up the script into an executable
[marto]: that'll do it
[james28909]: im glad im not in charge of anything important, like filling up peanut butter jars
