Sum of numbers.

The fundamental insight that originally led to the creation of this formula probably started with the observation that the sum of the first term and last term in an arithmetic series is always the same as the sum of the 2nd and 2nd-to-last, 3rd and 3rd-to-last, etc. Try it in your head with a simple series, such as whole numbers from 1 to 10 ...

First, round up the first number to the nearest 10's place value ie., 567 to 570. 570+349. Now, round up the second number to the nearest 10's place value ie., 349 to 350. 570+350. Add 570 and 350. = 920. 567+349≈920. ∴ The Estimated Sum of 567+349 is 920.To get the sum of N numbers using a while loop: Iterate for as long as the number is greater than 0.
