<p>Royal titles, such as Henry I, Henry II, and so on, often use Roman numerals. Have you noticed the names and wondered what these<a>symbols</a>(I and II) represented? Those are the Roman numerals. Earlier, people used fingers, sticks, bones, etc., to count. When life became complex, a<a>standard form</a>was required to count. Ancient Romans used the Roman numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.</p>
