8 <p>We can see that the number X refers to 10 and the other number refers to 2. So in this, the smaller numeral is after the large numeral, so we need to add the 10 and 2 to get the value 12.</p>

11 <h3>The Roman Numeral can be repeated up to three times to increase its value. The numbers cannot be repeated after three times. Only symbols like I, X, C, and M can be repeated and V, L, and D cannot be repeated.<p>Example: XXX = 10 + 10 + 10 = 30 repeating the numeral X for the fourth time is not allowed.</p>

14 <p>If the smaller numeral comes before the large numeral, then we need to subtract the smaller numeral from the larger numeral to get the number. There are three rules in<a>subtraction</a>, they are: I can be subtracted from V and X. X can be subtracted from L and C. C can be subtracted from D and M.<p>Example: In the number IV.</p>

15 <p>Here, V is the biggest numeral and I is the smallest numeral. As we see that the smaller numeral is before the larger numeral, we need to subtract to get the number. V (5) - I (1) = IV (4).</p>

18 <p>Roman Numerals consist of several limitations, they are: A numeral cannot be repeated more than three times. For example, III (3) cannot be repeated more than 3 times, instead we use IV for writing 4.</p>

19 <p>Subtraction cannot be done with the non-pair numbers. For example, XI here X (10) - I(1) gives IX is applicable but IC, C (100) - I(1) is not applicable.</p>

20 <p>Only one subtraction can be allowed in one numeral. For example, XL (40), L (50) - X (10) is applicable to get 40 but XXL is not applicable to get the number 30.</p>
