How to sum multiple results from a predicate in prolog?

Question

So I have a predicate that sometimes returns more than one numerical result, eg.

X=3;

X=1

How can I sum multiple return values together? On oc

Answer 1

You didnt show us code so i cant tell exactly what is correct solution, but you can try with findall/3 or bagof/3 predicates to collect results in list and then sum them all.
