<p>In ancient times, people counted using fingers, sticks, bones, etc. As life became complex, a standardized form was required for counting, leading to the development<a>of</a>the Roman Numeral system. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used for counting.</p>
