How to solve the problem of selecting terms for the desired sum in Prolog?

Question

Prolog

You need to calculate how many ways you can choose the amount equal to 18, using the following terms: 10,6,1. At the same time, the same terms in a different order are different ways (for example, 10+6+1+1 and 10+1+6+1).

Answer 1

You need to read about Newton's binomial. There is no need for a prologue.
