This kid should just say “frig it” and hand in a blank piece of paper and take his C.
Question one is deemed wrong because the teacher wanted 3+3+3+3+3 instead of 5+5+5 when the 5 was mentioned 1st in the question.
When the 4 is mentioned 1st in question 2, the student does 6 arrays. The teacher changes gears and says she wanted the first number to represent the arrays.
It seems that whatever the kid did it would be wrong.
