# Number Theory Revealed: The Seriesby Andrew Granville There will be four books in this trilogy:

1. An elementary book in two versions: Number Theory Revealed: An Introduction and Number Theory Revealed: A Masterclass (published in 2019).
2. Followed by an introduction to analytic number theory: Analytic number theory revealed: The distribution of prime numbers.
3. Complemented by an introduction to solutions of equations of low degree: Arithmetic Geometry Revealed: Rational Points on Curves, and Modular Forms.
4. And finally, the author will revisit one of the great classics, Gauss's Disquisitiones Arithmeticae Revealed.
