## Converting Roman Numerals to Numbers

Romans used these letters for Unit place numbers that are the same for all numbers for their Unit place.

- I for 1
- II for 2
- III for 3
- IV for 4
- V for 5
- VI for 6
- VII for 7
- VIII for 8
- IX for 9

Each number has 1 to 9 digits in a Unit placed in numbers, only the tenth, hundredth, thousand places, etc. are changed each time.

There is a simple rule to write this number, suppose you have to write 11 in roman numerals, then you have to write its tenth and unit place numbers in roman numerals. 11 is the sum of 10+1, X is used to present 10, and I is used to giving 1, so the number is XI.

**Rule 1:** If there is a larger number in the form of tens, hundreds, etc., then the number after it is added separately.

- VIII = 8 (5+1+1+1)
- LX = 60 (50+10)
- MCC = 1200 (1000+100+100)

**Rule 2:** If there is a smaller number in the form of tens, hundreds, etc., then the number after that is subtracted from the leftmost number.

- IV = 4 (5-1)
- IX = 9 (10-1)
- XL = 40 (50-10)

## Solved Examples

**Ex 1:** Write 88 in roman numerals

**Solution:**

88 = 50 + 10 + 10 + 10 + 5 + 1 + 1 + 1

= LXXXVIII

**Ex 2:** Convert 569 into roman numerals

**Solution:**

569 = 500 + 50 + 10 + 9

= DLXIX

**Ex 3:** 79 in roman numerals

**Solution:**

79 = 50 + 10 + 10 + 10 – 1

50 = L

10 = X

10 – 1 = IX

So, 50 + 10 + 10 + 10 – 1 = LXXIX

**Ex 4:** Convert XCIII roman numerals into numbers

**Solution:**

XC = 100 – 10 = 90

III = 3

So, XCIII is 93

**Ex 5:** 1000 in roman numerals

**Solution:**

1000 = M

M is used to represent 1000

**Ex 6:** 10000 in roman numerals

**Solution:**

10000 = X̅

**Ex 7:** 101 in roman numerals

**Solution:**

101 = 100 + 1

100 = C

1 = I

= CI

**Ex 8:** 11 in roman numerals

**Solution:**

11 = 10 + 1

10 = X

1 = I

= XI

**Ex 9:** 111 in roman numerals

**Solution:**

111 = 100 + 10 + 1

100 = C

10 = X

1 = I

= CXI

**Ex 10:** 13 in roman numerals

**Solution:**

13 = 10 + 3

10 = X

3 = III

= XIII

**Ex 11:** 14 in roman numerals

**Solution:**

14 = 10 + 4

10 = X

4 = 5 – 4 = V – I = IV

**Ex 12:** 15 in roman numerals

**Solution:**

15 = 10 + 5

10 = X

5 = V

= XV

**Ex 13:** 16 in roman numerals

**Solution:**

16 = 10 + 5 + 1

10 = X

5 = V

1 = I

= XVI

**Ex 14:** 17 in roman numerals

Solution:

17 = 10 + 5 + 2

10 = X

5 = V

2 = II

= XVII

**Ex 15:** 18 in roman numerals

Solution:

18 = 10 + 5 + 3

10 = X

5 = V

3 = III

= XVIII

**Ex 16:** 19 in roman numerals

Solution:

19 = 10 + 9

10 = X

9 = IX

= XIX

**Ex 17:** 1942 in roman numerals

Solution:

1942 = 1000 + 900 + 40 + 2

1942 = 1000 + (1000 – 100) + (50 – 10) + (1 + 1)

1000 = M

900 = 1000 – 100 = M – C = CM

40 = 50 – 10 = L – X = XL

2 = II

= MCMXLII

**Ex 18:** 1957 in roman numerals

Solution:

1957 = 1000 + 900 + 50 + 5 + 2

1000 = M

900 = 1000 – 100 = M – C = CM

50 = L

5 = V

2 = II

1957 = MCMLVII

**Ex 19:** 1963 in roman numerals

Solution:

1963 = 1000 + 900 + 50 + 10 + 3

1963 = 1000 + (1000 – 100) + 50 + 10 + (1+1+1)

1963 = M + (M – C) + L + X + III

1963 = M + CM + L + X + III

1963 = MCMLXIII

**Ex 20:** 1964 in roman numerals

Solution:

1964 = 1000 + 900 + 50 + 10 + 4

1964 = 1000 + (1000 – 100) + 50 + 10 + (5 – 1)

1964 = M + (M – C) + L + X + (V – I)

1964 = M + CM + L + X + IV

1964 = MCMLXIV

**Ex 21:** 569 in roman numerals

Solution:

569 = 500 + 50 + 10 + 9

569 = D + L + X + IX

569 = DLXIX
