i dont get the problem, when people dont understand homework questions they (as in my friends and I did) go to the teachers for help and they walk you through the question
it's not as if Milja doesn't understand the method and working out? Sis said she could follow it and understand it so they know how to do similar questions in the future
also idk if Milja did the rest of the questions on that paper (and I'm assuming so) then but they look just as hard if not harder so it's p apparent that Milja's more than capable
like i can only assume milja (back me up milja) just simply struggled on those types of questions bc if you look you'd see that those questions are super similar
