Quadratic Reciprocity

This app provides an introduction to quadratic residues leading up to the Quadratic Reciprocity law. It also implements an algorithm for determining quadratic residues using this law. Further, when this algorithm is run it provides a step-by-step explanation of the results.

While a grasp of some advanced math is required to fully appreciate the quadratic reciprocity law, at one level it can be understood in terms of elementary number theory. Our goal is to make this exposition accessible to both levels of readers.

The app makes use of Latex and MathJax to present the mathematics with standard notation, and uses the app's programming capabilities to implement the algorithm. It does not require an internet connection and works completely offline.
