In this contribution we deal with the sum of the series of reciprocals of the cubic polynomials with different positive integer roots. We derive the formula for the sum of these series and verify it by some examples using the basic programming language of the computer algebra system Maple 16. This paper can be an inspiration for teachers who are teaching the topic Infinite series or as a subject matter for work with talented students.
