How do you get negative points on it should be impossible

It's probably because some questions you answered get deleted :/ i have the same problem

Explanation:

its actully posible it happend to me once. so if your acc gets banned or your questions/answers its will take away your points and you will be left with the number of points you had before it got banned or delted. so for example i had around 500 points so you would have to answer questions untill you out of the negative :)

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.
