*** rule 1 is REALLY IMPORTANT. It means we have an infinite number of letters, not only I .. M, which means we can represent as large numbers as we wish to

The rest below is just for the sake of being pedantic enough :)

*** rule 2 is incorrect about non-powers-of-10. There can be 3 or less identical symbols (in a row) if they denote 10^k, and no identical symbols otherwise, not 2.

*** rule 5 actually says: Ai >= Ai+2, and Ai+1 can be anything,  but if it's larger than Ai, then Ai > Ai+2, not >=

*** rule 4 means that for some i there can only be a signle j that j < i and Aj < Ai (another interpretation is that there can be no 2 smaller numerals *immediately* before some numeral, which in fact implies from rule 5)
