Easiest way to Learn Roman Numbers
In Rome, there are a number systems that consist of Roman numerals. These numerals are just the combination of Latin alphabets and taken in use to signify the values. The charts and tables of roman numerals 1-100 are available on the Toppers Bulletin. Here are how to learn roman numerals?
Ancient Romans applied a unique rule of showing numbers
For Examples:
In Roman numerals, 1 is written as I
and 2 is written as II.
The Roman Symbols
The Roman numerals are based upon counting. The letter I, meaning 1, could be a notch on the stick. The other letters V, X, L, C, and M, are typically easy to learn.
| Number | Roman Numeral |
| 1 | I |
| 5 | V |
| 10 | X |
| 50 | L |
| 100 | C |
| 500 | D |
| 1000 | M |
Roman Numerals- The Rules
When a smaller numeral such as I or X placed after a larger (or equal) one has the effect of added(plus)
- Example: VII = V + I + I = 5 + 1 + 1 = 7
- Example: LXXX = L + X + X + X = 50 + 10 + 10 +10 = 80
But a smaller numeral such as I or X placed before a larger one has the effect of subtracted(minus)
- Example: IV = V − I = 5 − 1 = 4
- Example: XIX = X − I + X = 10 − 1 + 10 = 19
Roman Numbers from 1 to 100
Tips of chart usage:
- Write numerals left to right, with the largest numeral first.
- The largest numeral possible is used at each stage.
- No more than three instances of same adjacent numeral. Occasionally number 4 is written not as IV but as IIII to add symmetry and balance to a watch or clock face.
Here are list of Roman numerals or numbers from 1 to 100.
Remember: I=1, V=5, X=10, L=50, C=100

How to Convert to Roman Numerals?
Separate the number into Thousands, Hundreds, Tens and Ones, and write down all in turn.
For example:
The year 1989 for example would be written MCMLXXXIX.
Divide 1989 into 1000, 900, 80 and 9, then do each conversion
- M is 1,000
- CM is 900,
- LXXX is 80(50+10+10+10),
- IX is 9.
1000 + 900 + 80 + 9 = 1989, so 1989 = MCMLXXXIX
