Both from experience with my kids and recent articles I've read, teachers purposely have bizzare ways of grading HW and tests. They give more credit for wrong answers with verbose confusing and explanations, than for correct answers explained by few or no words.

People who are good at math can do things quickly and efficiently in their heads and don't need to try to use many words to explain their correct answers to brain-dead teachers. To penalize, rather than reward, such talent is bizarre.

teachers purposely have bizzare ways of grading HW

Almost all of my teachers grade homework for completion rather than accuracy, meaning you get 10 points just for doing it even though all your answers could be wrong. (They don't want to hurt anyone's "self-esteem" and give them the F they deserve, so everyone gets the same grade...socialism at work.) Anyway, that sparks grade inflation and makes grades look better ad my school system loves to brag about their "high" grades.

It's been a couple of decades now, but that's still something I remember from attending government schools. More than once my math tests or homework were marked down because, "you didn't show your steps". Just sheer idiocy! The fact that someone can work something out in their head and get the right answer is the surest indication that they have mastered the subject matter.
