Number theory in secondary schools’ mathematics

open access: yesLietuvos Matematikos Rinkinys, 2021
Schools’ curricula are analyzed in terms of Number Theory.  We deduce,  that the concept of number is first and main in secondary schools’ Mathematics.  The problems of divisibility of numbers are also discussed, the examples of such problems are given.

Fermat Numbers and Mersenne Numbers [PDF]

open access: yesMathematics of Computation, 1964
This paper gives details of the computations made on an IBM 7090 computer to show that the Fermat number \(F_m = 2^{2^m} +1\) is composite for \(m=14\), and that all the Mersenne numbers \(M_p=2^p-1\) \((5000 < p < 6000)\) are composite. The method used to show that the Fermat number is composite was to compute \(3^{2^n}\) modulo \(F_m\).
