What is the number 4000 in roman numerals?

Answer 1

Although MMMM is intrinsically correct, it breaks the accepted convention that states no symbol may be repeated more than 3 times. Thus the upper limit using this convention is 3999 (MMMCMXCIX).

However, using Middle Age notation, we can place a horizontal bar over any value to multiply it by 1,000. Thus 4000 is 4 x 1000, and can be notated as follows:

__

IV

Another form of notation, also from the Middle Ages, uses the original symbols for D and M. With these symbols it is possible to make 4,000 using 1500+1500+1000, which would be written as follows:

CIƆƆCIƆƆCIƆ

This form of notation can also be written as follows:

ↀƆↀƆↀ
