Can't find anything on this anywhere.

I'm trying to balance out my logbook to make sure all the times equal out to what they should be. I'm having a hard time figuring out what times should compare to what.

Does Dual Received + PIC Time = Total Flight Time?
Does Dual Received - Simulated Instrument = PIC

etc.

Is there anything I should look for, like the above, to double check my flight times?

Thanks!
