3 <p>The ancient Romans used a numeric system that consisted of a collection of symbols. Today, we call it the Roman numeric system. Today Roman numerals are used in music theory, chapters, and even in clocks. In this topic, we are going to learn more about Roman numerals from 100 to 200.</p>

4 <h2>Roman Numerals 100 to 200</h2>

5 <p>Numbers in the Roman numeric system are represented using special<a>symbols</a>. I, V, X, L, C, D, and M are the seven symbols that were used by ancient Romans. When writing Roman numerals a few rules are followed. If a lower digit value is written to the right of a higher-value digit, we would need to add the two digits.</p>

6 <p>For example, XXV we would add the values because V (5) is<a>less than</a>X (10). Such rules are the building blocks of the Roman numeric system. </p>

8 <p>Numbers from 100 to 200 are represented slightly differently when compared to<a>numbers</a>from 1 to 100. For example, we represent 100 with the symbol C. Here we have a chart to help you understand the numerals from 100 to 200 for better understanding. </p>

49 <p>In the Roman numeric system, when a bigger symbol such as C or X comes before a smaller symbol like I, we will add the values.</p>

48 <p>In the Roman numeric system, when a bigger symbol such as C or X comes before a smaller symbol like I, we will add the values.</p>

50 <p>Example: If the given number is CXX. As we know the symbol C represents the number 100 and 20 is represented by XX. Since 20 is smaller and after the larger numeral which is C, we need to add the two numbers together. Once added we will get the value 120. </p>

51 <h2>Rule 2: Repetition Method</h2>

50 <h2>Rule 2: Repetition Method</h2>

52 <p>In Roman Numerals a symbol can be repeated only up to three times, this would increase its value accordingly. I, X, C, and M are symbols that can be repeated to increase their value. However, V, L, and D are symbols that cannot be repeated more than once. For example, the Roman numeral symbol that represents the number 100 can be repeated three times CCC to make the number 300. </p>

55 <p>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>

54 <p>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>

56 <p>Example: In the number IX. Here, X 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. X (10) - I (1) = IX (9). </p>
