<p>To meet their daily commerce and administration needs, the ancient Romans developed Roman Numerals. It used a combination of seven symbols - I, V, X, L, C, D, and M to represent numbers. Roman numerals were used to record transactions, keep track of data, and label military units. In this topic, we are going to learn about the Roman numeral XXXIX.</p>
