You're correct. There are several mnemonics that work. Some people find GEMS a little easier to remember.

Though honestly it varies what exactly i use, usually i'll just smear brackets all over the page to help me understand whatever the hell i have infront of me, even if the bracket wouldn't make a difference in the calculation (especially useful in physics class once you get to the point where calculating something turns into a giant block of formulas)

Do a bunch of algebra and GEMS becomes second nature.
Do a bunch of coding and operations become bit shifts anyway.

Learning that I could divide by bit shifting changed my life.

With two's compliment and repetition you can divide by addition.

I always learned PEMDAS and PEDMAS

The biggest fail are the r/confidentlyincorrect crowd who don’t understand the ambiguity rules.
PEMDAS works just fine, just don’t forget ambiguity rules.

What are they

I think everyone agrees with this.
The PROBLEM is when we have something like 8 ÷ 2 (2 + 2), and whether the first 2 is part of the grouping with implied multiplication or not. Which is why, you would never get it written like that, but rather as a fraction that clearly shows where what belongs.

Of course it's part of the multiplication. If it wasn't there would be another symbol there.

Is it bad i only know bidmas - brackets indices division multiplication addition subtraction?

Enough memes about elementary school math.

Should it not be GEMA?

Does anyone past secondary school actually need these? Like either you already know this by hart or you don't need it.

I might be dumb but isn't this exactly how you're supposed to do it? At least that's how i learned it in school.
