So I'm in math in 9th grade and my whole class is in Algebra 1 and I'm in algebra 2 so I'm kind of a genius and I go around checking everyone's work and my teacher ( like most teachers) doesn't know much about math but as I go around class I get to the teaches daughter and I watch her work out the problem and i just face palm then I raise my hand and say excuse me but Summer (that's her name) just got -0 for her answer. And the whole class burst out laughing and so did the teacher. Lol stupid people are not smart.
