Sum of numbers.

Summing the Numbers From 1 to n. By writing the number 1 − n and then repeating them backwards below, we can see that all of our pairs add up to n + 1. There are now n lots of n + 1 in our picture, but we got these using the numbers 1 - n twice (once forwards, one in reverse), hence to get our answer, we need to halve this total.
