The advantages of the ancient Roman numeral system were and still are as follows:-

1 It needs less main numerals than the Hindu-Arabic numeral system

2 It doesn't need a zero symbol for operational purposes

3 It's easily capable of addition

4 It's easily capable of subtraction

5 It's easily capable of multiplication

6 It's easily capable of division

7 It can easily worked out on an abacus calculating device

8 It doesn't use decimals

9 It uses fractions but only to a limited extent

10 It can be in additional format as for example DC = 600

11 It can be in subtractional format as for example CD = 400

12 Its numerals and fractions are all rational numbers

13 Its numerals are easily recognised for positional place value purposes

14 It uses brackets for multiplication as for example (X) = 10,000

15 It uses exponents as for example (M)M = 1,000,000,000

16 It was the most advanced numeracy system in the ancient known world

17 It's still used today albeit misrepresented

18 It makes mathematical sense when represented properly

19 It needed only 5 symbols at one time because (I) = 1000 and I) = 500

20 It can sometimes be abridged thus using less numerals but of equal value

21 Its symbols follow a regular pattern of ... 5, 2, 5, 2, 5, 2 ...

22 Its 7 main symbols today are: I, V, X, L, C, D and M

23 It therefore follows that even today it still has many advantages
