Abstract

This article delves into several core conclusions related to the density of real numbers, employing constructive methods to provide rigorous proofs. The overall thought process is clear, the logic is stringent, and the language is simple and easy to understand, aiming to offer readers an intuitive and profound way of understanding. Through specific constructive examples, the article not only showcases the unique charm of constructive methods in proving the density of real numbers but also further reveals the intrinsic structure and properties of the real number system. Whether for mathematics students or for the general mathematics enthusiasts, this article has certain reference value and inspirational significance.
