NEGATIVE ONE BOTTLES OF BEER ON THE WALL, NEGATIVE ONE BOTTLES OF BEER—everybody! TAKE ONE DOWN, DIE IN THE EXPLOSION RESULTING FROM THE ANNIHILATION OF MATTER AND ANTIMATTER UNLESS YOU LIVE ON A PLANET MADE OF ANTIMATTER IN WHICH CASE I GUESS IT'S OKAY...ZERO BOTTLES OF BEER ON THE WALL!!

Gauss' problem can also be seen this way: Take the median and multiply it by the number of numbers. The median of 1-99 is 50, 50*99+100 = 5050. Or you could say the median of 1-100 is 50.5, 50.5*100=5050.

This is the same principle as that the sum of any sequence is the mean multiplied by the number of numbers, and when the numbers are consecutive, the mean and the median are the same thing.

I teach math....I try to make it as interesting as possible; however, because many students aren't used to thinking outside of the box, they are afraid to take risks and thus, hinder their own education. We'll get there one day, America.

This method of adding all numbers within a finite set is also defined by the formula for the sum of an arithmetic sequence: (N/2)(A1 + AN) The number of terms divided by two times the first term plus the last term.
