The Roman numeral X represents X as in Class X
The Roman numeral C represents 100
When X is written to the left of C it means 100 less 10 = 90
When X is written to the right of C it means 100 plus 10 = 110

X = 10 and C = 100 but X before C means 10 less than 100. Therefore, XC = 90 in the same way that IV = 4 (1 less than 5) and IX = 9 (1 less than 10) Hope that helps!
