Hello everyone,
I was just wondering how to find the values for P, I, and D when working with a PIDSubsystem in C++. Does anyone have these values/understand how to find them? I am currently not in Calculus, I am in Pre-Calculus, so I have no idea what a derivative is. Thanks!

Someone else's values won't help you.

Those are tuning parameters, and they are unique to your application.

Here are some tutorials for you:
