How would I convert the roman number MXC to arabic?
I know that M=1000, X=10, and C=100 but there are all these rules about adding and subtracting depending on the order and I don't understand. Can someone help? Thanks.

MXC is 1090.
The X is subtracted from the C because it's smaller, so that becomes 90. This is added to the M because M is larger than this value.
(I'm sure someone can explain it better than I can....)

Larger vs smaller is also affected by the position of X, X is before C so it is subtracted from C (larger) and if it is after It is added
