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:

Example valid values:


Data validation

n must be a natural number greater than 0.


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