The accepted convention does not permit values over MMMCMXCIX (3999) to be notated in Roman numerals (the letter M cannot be repeated more than 3 times). Breaking with convention, MMMMD would be 4500.
In the middle ages, an overline would multiply the value by 1,000, while vertical lines either side of a numeral multiplied the numeral by 100. Using that convention, we could represent 4500 as 45 * 100 which would be |VL|
In roman numerals, numbers greater than 3999 use parentheses around, or a horizontal line above, the numbers that are multiplied by 1000. Writing 3999 is written as MMMCMXCIX, but the number 4500 would be written as (IV)D.
MMMMD or as D(V) D(V) = -500+1000*5 = 4500
You write 1533 in roman numerals like this: MDXXXIII
To write 19000 in Roman numerals, combine the Roman numerals for 1000 (M) and 9000 (IX). Therefore, 19000 in Roman numerals is written as MXCM.
To write twenty in Roman numerals, you simply write the letter X.
