Still on my wishlist, but it is promising. The smaller kindles don't let me see enough of PDFs for technical sections.

**Formula:**`S = n(n + 1)/2`

## Introduction to Sum of Natural Numbers Calculator

The sum of the first *n* natural numbers is calculated by the formula *S = n(n + 1)/2*. This formula provides a quick way to sum up all natural numbers from 1 to *n*, where *n* is a positive integer. The concept originates from Gauss's observation in elementary arithmetic.

## Parameter usage:

`n`

= upper limit of the natural numbers to be summed

## Example valid values:

`n`

= 10`n`

= 100

## Output:

`sum`

= sum of the natural numbers up to`n`

## Data validation

*n* must be a natural number greater than 0.

## Summary

This calculator efficiently computes the sum of the first *n* natural numbers, demonstrating a foundational mathematical property used in various computations and formulas.
