What are the steps to follow in changing a Hindu-arabic numeral to roman numeral?

Answer 1

to understand roman numerals first you need to know how to indicate a amount

first of all

I meens1

Vmeans5

Xmeans10

L means 50

C means 100

D means 500

M means 1000

you put the amount the numerals in order of the highest to lowest so for say

333 you write CCCXXXIII but you cant put more than 3 of the same numerals in a row

to indicate number like 400 you put a number of a lower rank in front of a higher rank number the only exception i M

so 4=IV 9=IX 40=XL 90=XC 400=CD 900=CM

but a important thing is that you can never put a numeral 3 ranks or lower before the higher numeral so 999=CMXCIX not IM

also for higher numbers you can thousandfold the number's worth by putting a horizontal line above it
