#1 Help Me ! » Sum of positive integers 0 to N » 2005-05-11 14:08:09

I am looking for different ways to answer this problem?

Want to find the sum of positive integers from 0 to N.

For example if N = 5 then

SUM = 0+1+2+3+4+5.

How do I solve if N = 1000

???

I found some interesting ways but looking for more ways to do it.
