<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 LXXXIV.</p>

<p>LXXXIV is the Roman numeral representation of 84. Here, L represents 50, X represents 10, V represents 5, and I represents 1. Thus, LXXXIV = 50 + 10 + 10 + 10 + (5 - 1) = 84. Therefore, LXXXIV represents the value 84 in Roman numerals.</p>
