Now I hate when people say that Polish is very logical like math when in fact there are so many rules and so many exception. That's like mocking the beauty of math you know! In math, you can just understand one or two basic rules and from those rules, you can pretty much get anything by yourself. That's also one of the mistakes most people make when learning math. They just memorize things, "fast" methods, etc.
Last friday, I learned quantifier in Polish. Consider you want to say this (in present tense): "Some students read", in Polish it would be "Paru/parę studentów/studentek czyta". So, we need to apply Dopełniacz case to the student and always the third person singular for the verb. So, that's when I asked my teacher why it's using the third person singular verb while it's clear that the number of students there is plural. Why don't just use the verb based on the quantifier itself? Aaand she just said that most Poles also make that mistake. Yeaah sure, the only thing I could do now is to "memorize" this. Polish is just like math! #sarcasm
