1 and 100 make a pair that add to 101
2 and 99 make a pair that add to 101
3 and 98 make a pair that add to 101
etc
50 and 51 make a pair that add to 101
So you have 50 pairs that add to 101
So the total sum is 50*101 or 5050.

What is the sum of the first 100 positive integers?
To find the sum of the first 100 integers, you first add 1 plus 100 (the first and last numbers of the set) and get 101. Do the same with the next two integers, 2 and 99 and you'll get 101. Since you are adding two integers at a time and there are 100 integers between 1 and 100, you'll get 101, fifty times. Therefore, a shortcut would be to simply multiply 101 times 50 and get 5,050.
