<p><strong>Rule 1: Addition Method -</strong>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 - LV(55) = L(50) + V(5)</p>

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

11
<p>L(50) + II(2) = LII(52) L(50) + III(3) = LIII(53) We can’t write LIIII for 54 , it's LIV (54)</p>

<p>L(50) + II(2) = LII(52) L(50) + III(3) = LIII(53) We can’t write LIIII for 54 , it's LIV (54)</p>
12
<p><strong>Rule 3: Subtraction Method -</strong>From the repetition method, we got to know that a symbol can’t be used more than 3 times, then how will we write LIV ? Here in Roman numerals, 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 LIV (54), there are two parts: L (50) and IV (4). 50 has a fixed symbol in Roman Numerals, i.e. “L” and IV (V - I). Which results in LIV (54) = L(50) + IV(4)</p>

<p><strong>Rule 4: Limitation Rule -</strong>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. </p>

<p><strong>Expansion Method:</strong>In this method, we will break the Roman numeral into smaller parts based on their values and then add them. For example LV is made up of 2 parts that are 50 and 5. 50 can be written as L. 5 can be written as V . Now if we add it L (50) + V(5) = LV(55).</p>
