I've always seen it explained as (100+0) + (99+1) + (98+2) + (97+3) + ...

So you basically have 50 pairs of numbers that all equal 100. So 5000 right? But there is one number that doesnt have a pair to make 100. Which is 50. Obviously there arent two 50s to make 100. So its added by itself. 5050.

Its the same as the summation of 1 to 10. (0+10) + (1+9) + (2+8) + (3+7) + (4+6) + 5. Its 55.

It works fantastically.

If you know where to look and where to tinker, then I think you have at least some understanding of what you're doing.

I had a package come from Japan to Cincinnati, Ohio, then to my city. Two days later it goes to Singapore. It comes back to the US but via Los Angeles this time. Then to Cincinnati and finally my city. I contacted DHL customer service, they tell me the shipper shouldnt provide me with false hope of an earlier delivery. But they never did, I was going off DHL's website and their estimated delivery date. Customer service then ended the chat before I could respond.... I try not to use them.
