I tried googling your acronym above, and found this from a Dutch site that I was able to translate to English:
https://www.mathematischinstituut.nl/artikelen/de-volgorde-van-bewerkingen/
"Dit lijkt wel een goede volgorde, maar als we nu terug gaan naar onze som van hierboven dan komen we onmiddelijk weer in de problemen. Want we weten dan vermenigvuldigen en delen voor optellen en aftrekken komt, maar hoe zit dat dan als we moeten kiezen tussen vermenigvuldigen en delen?
In dit geval kiezen we voor de meest linker operatie. We gaan dus door de rekensom heen zoals we een zin lezen, van links naar rechts."
"This seems like a good order, but if we go back to our sum above then we will get back into trouble. For we then know multiplying and dividing for addition and subtraction comes, but what is it when we have to choose between multiplying and dividing?
In this case, we choose the leftmost operation. So we go through the calculation as we read a sentence from left to right."
Seems to be the exact same thing as PEMDAS, which is also mentioned in the very first line of that site.
