The world has a lot of different standards for a lot of things, but I have never heard of a place with the default screw thread direction being opposite.
So does each language have a fun mnemonic?

The Right Hand Rule (RHR). Point the thumb of your right hand in the direction you want something to go. Curl your fingers. That is the direction of rotation. Translate to any language which has hands.
The only thing I don't like about this is the implication of a left hand rule for left hand threads, which makes my E&M physics brain sad
Multliply bu -1. Same as with negative charge
Right, for a paper physics problem. Try telling someone to multiply their hand by -1.
Flip your hand over
