Ok than I guess according to you PEMDSA doesn’t work

Oh course it does, and I have no idea why you think I would think otherwise! 😂

Or what about PEDMAS or PEDMSA maybe?

Yep, they all work

Oh wait we made up that order cuz it’s easier to say?

No, you made it up because your country has a chip on it's shoulder about doing it the same way as the rest of the world. 🙄
