Hi Mayson,
In this case it's not necessary to use a variable. Factor's stack is more
than sufficient for a problem like this. There's also a word that will help
you: reduce. Try \ reduce help in the listener and I think you'll find the
problem a lot easier.
If you were using a variable, then at some point you would use either
with-scope or with-variable so that you're not using a global.
