# What is 111X in roman numerals

There is no Roman Numeral value for this particular set.

111 (one hundred eleven) is CXI in Roman Numerals and the Roman Numeral X is equivalent to 10.

There are four basic principles for reading and writing Roman numerals:

1. A letter repeats its value that many times (XXX = 30, CC = 200, etc.). A letter can only be repeated three times.

2. If one or more letters are placed after another letter of greater value, add that amount.

#### MCC = 1200 (1000 + 100 + 100 = 1200)

3. If a letter is placed before another letter of greater value, subtract that amount.

#### CM = 900 (1000 – 100 = 900)

Several rules apply for subtracting amounts from Roman numerals:

a. Only subtract powers of ten (I, X, or C, but not V or L)

#### DO write XCV (XC + V or 90 + 5)

b. Only subtract one number from another.

#### DO write XIII (X + I + I + I or 10 + 3)

c. Do not subtract a number from one that is more than 10 times greater (that is, you can subtract 1 from 10 [IX] but not 1 from 20—there is no such number as IXX.)

#### DO write XCIX (XC + IX or 90 + 9)

4. A bar placed on top of a letter or string of letters increases the numeral's value by 1,000 times.
