The history of mathematics. Mathematics in history

The text is the first of two volumes dedicated to the Theory of Numbers, one of the branches of mathematics that has historically produced questions of considerable interest, such as Fermat's Last Theorem and the still unresolved Riemann Hypothesis, on the distribution of prime numbers, and which has several applications for example in the security of cryptographic systems for the secret transmission of data.
The issues addressed in the text, which are outside the guidelines of traditional scholastic programs, concern the principle of induction and some of its equivalent formulations, the problem of divisibility and factoring of integers, the theory of p-adica evaluation and some types of diophantine equations such as the linear equations and the equations of Pell. The book is accompanied by over 200 examples and exercises, some of which are taken from national mathematical competitions.
The book aims to provide teachers and students of secondary schools of medium-level tools of the theory of numbers needed to address national and international mathematical competitions and mathematical tests of access to the University Schools of Excellence. Thanks to the choice of the topics addressed, the text lends itself to be used also in the university courses of elementary Algebra.

Salvatore Damantino, a graduate in mathematics, has been teaching since 2008 and since 2015 he is a lecturer at the "Fermo Solari" Institute of Tolmezzo UD. From 2017 he is President of the Mathesis section of Udine for which he organizes training activities for teachers and students, and math competitions. Speaker at some conferences of the Italian Mathematical Union as part of the National Mathematics Olympics project, he regularly holds lessons in internships for secondary school students and has published texts on problem-solving.
