Hi Prestonator,
It’s always good to dive right in and learn something new! I’ve found that, while working with blueprints, it becomes easier each time you use them to see the flow of logic. If you want to add two variables, for example, it is easy to create a X + Y node of whatever var types you need. If you need additional information or just want to see how other users are tackling specific tasks, take a look at the wiki, it has a ton of tutorials and videos, many of which are specifically for blueprints.
