UNIQUE PROCESS OF SUMMATION BY GAUSS -TIT

Johann Carl Friedrich Gauss was a German mathematician and physicist who made significant contributions to many fields in mathematics and sciences. 

Once their teacher asked the class to solve a question. The question was, sum up-to 100 from 1. Everyone in the class started to add 1+2+3... like that.

Child Gauss did the sum within few minutes. The process he followed was unique and enough to impress his teacher.
