1 Rule 1: Addition Method -In the<a>addition</a>method, you will combine different Roman numerals. When a smaller or the same number is placed after the larger number, we will simply add it - X (10) + V (5) = XV(15)(10 and 5 have fixed notations in Roman Numerals)

2 Rule 2: Repetition Method -In this method, a Roman Numeral can only be used up to 3 times to get a larger value

3 X - 10 X + I = XI(11) X + I + I = XII (12) X + I + I + I = XIII(13) We can’t write XIIII for 14,it's XIV (14)

4 Rule 3: Subtraction Method -From the repetition method, we got to know that a symbol can’t be used more than 3 times, then how will we write 14 ? Here, we will use the<a>subtraction</a>method. If the smaller numeral is placed before the larger numeral, then you have to subtract the smaller numeral from the larger numeral. For example, in XIV (14), there are two parts: X (10) and IV (4). Here, IV is obtained by subtracting I (1) from V (5), which equals 4. Together, this forms XIV (14).

5 Rule 4: Limitation Rule -In Roman numerals we can't repeat a number more than 3 times.after that,we have to use different symbols here you will use<a>addition and subtraction</a>methods. For example - we can't write 4 as IIII, instead we write IV (subtraction method subtracting I(1) from V(5) to get IV(4). For 10, we use X. Here, we can't use VV because there are specific letters assigned to the values, for example (V - 5, X- 10, L - 50, C - 100, D - 500, M - 1000) we have to use these symbols for the specific values. These rules make it easy for us to use the numeral system.
