<p>Those are Roman numerals. Earlier, people used fingers, sticks, bones, etc., to count. When life became more 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>

<h3>Explanation</h3>
44
<p>The transaction involves CL books (150 books), each valued at IV coins (4 coins). Therefore, the total amount of coins is calculated as CL × IV, which is 150 × 4 = 600. In Roman numerals, 600 is written as DC. </p>

<h3>Explanation</h3>

<h3>Explanation</h3>
51
<p>To determine the number of coins per friend, we divide the total number of coins by the number of friends: DXXIV / XXIV. In numbers, DXXIV is 524 and XXIV is 24. Thus, 524 ÷ 24 = 21. In Roman numerals, 21 is written as XXI. </p>
