I‘m assuming you checked ecosystem and forum and didn‘t find the math actions you were looking for. Then, I would take an action like float add, and use this to create a Custom Action where you can then plug in an as complicated formula as you like, in the code. This takes little/next to none coding experience. To get started find the guide in my signature, or checkout the Custom Action Wizard in the top menu under Playmaker in Unity (the menu is confusing, so I don‘t know where exactly it is, but it‘s there).
