OP: What's 2 plus 2?
SO: In what context?
SO: It would help if you tried first and gave some sample code
OP: I have two cats and two dogs and I wish to solve for total animals
SO: Just count them one by one, it's more general
OP: Well I would but I have the numbers 2 and 2 because one routine returns cat count, and the other the count of dogs
SO: Use The Plus library <github repo link>
