<p>In Roman Numerals, if the smaller numeral comes after the large numeral, then we need to add their values. Example: If the given number is MCC. We can see that the number M refers to 1000 and the other numbers refer to 200. So in this, the smaller numeral is after the large numeral, so we need to add the 1000 and 200 to get the value 1200.</p>

<p>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. Example: MMM = 1000 + 1000 + 1000 = 3000 repeating the numeral M for the fourth time is not allowed.</p>

<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. Example: In the number CM. Here, M is the biggest numeral and C is the smallest numeral. As we see that the smaller numeral is before the larger numeral, we need to subtract to get the number. M (1000) - C (100) = CM (900).</p>

<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. Subtraction cannot be done with the non-pair numbers. For example, XC here X (10) - C(100) gives XC is applicable but IC, C (100) - I(1) is not applicable. Only one subtraction can be allowed in one numeral. For example, CM (900), M (1000) - C (100) is applicable to get 900 but CCM is not applicable to get the number 800.</p>
