The score of a math exam stipulates that 90 points should be counted as plus five, so how much should 83 points be counted? The scores of five students are: negative 2, positive 1.
The topic is not rigorous.

If the scales are the same, the starting point moves and the origin (recorded as 0) is 85 points.

83 is -2,

The average score of five people is 85+(-2+ 1+8+4-3)/5=86.6.

The topic is not rigorous because there is no regulation on the scale. For example, if five points are recorded as a unit, 90=+ 5, 85=+ 4 and 65 = 0.

Completely changed.
