<p>In Roman Numerals, if the smaller numeral comes after the large numeral, then we need to add their values.</p>

<p>Example: If the given number is VIII. We can see that the number V refers to 5 and the other number refers to 3. So in this, the smaller numeral is after the large numeral, so we need to add the 5 and 3 to get the value 8.</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 and X can be repeated and V cannot be repeated.</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 two rules in<a>subtraction</a>, they are, I can be subtracted from V and X.</p>

<p>Example: In the number IV. 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>

<p>For example, III (3) cannot be repeated more than 3 times, instead, we use IV for writing 4. Subtraction cannot be done with non-pair numbers.</p>

<p>For example, XI here X(10) - I(1) gives IX is applicable but IC is not applicable. Only one subtraction can be allowed in one numeral.</p>
