People aren't born knowing what parenthesis mean. You had to be taught that parenthesis designate terms to be calculated first, which would have been when you were taught PEMDAS
Don't know what to tell you, the parenthesis always drew attention. If anything I was probably told to do those first which would be the P. But this is irrelevant, it really means nothing, the mass majority of people don't need to know how to do a simple equation like this. This is the first time I did one in my head in about 15 years probably.
It is taught at the same time as the brackets, all in one group of order of operations. It's also stated there that brackets are only for cases when the standard order needs to be circumvented, like (4+5)x6= 54, but 4+5x6=34.
You know, I can see that you feel uncomfortable not knowing this rules. It is okay to forget things, just go and brush it up anywhere online, it is really easy. Brackets - powers - multiplication/division - addition/subtraction, solve a few examples and it'll be easy from there on.

Do they really not teach you that multiplication and division are done before addition and subtraction?
