Chapter

## Abstract

Until now this book has been concerned primarily with , where the elements

*multiplicative number theory*, a study of arithmetical functions related to prime factorization of integers. We turn now to another branch of number theory called*additive number theory.*A basic problem here is that of expressing a given positive integer*n*as a sum of integers from some given set*A*, say$$A = \left\{ {{a_1},{a_2},...} \right\}$$

*a*_{ i }are special numbers such as primes, squares, cubes, triangular numbers, etc. Each representation of*n*as a sum of elements of*A*is called a*partition*of*n*and we are interested in the arithmetical function*A(n)*which counts the number of partitions of i into summands taken from*A*. We illustrate with some famous examples.## Keywords
