<p>In royal titles, such as Henry I, Henry II, and so on, the Roman numerals are used to signify the order. Earlier, people counted using fingers, sticks, bones, etc. As life became more complex, a<a>standard form</a>was required for counting. Ancient Romans used the Roman numeral system for this purpose. The<a>symbols</a>are I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).</p>
