Counting Natural and Integer Solutions to Equations and Inequalities


Aleksa Srdanov, Dragan Stojiljkovic
Abstract

In this paper, formulas for the purpose of counting both natural number and integer solutions to linear equations and inequalities will be gradually derived using combinations with repetitions. General formulas will be derived and each solution will be additionally generalized.

Keywords
elementary combinatorics, combinations with repetitions.
