L represents 50 in Roman numerals. However, in the case of 45, we use a smaller value, as we are subtracting 10 from 50.
X represents 10 in Roman numerals. To denote 40, we place X before L (50), resulting in XL, representing 10 less than 50.
V represents 5 in Roman numerals. It follows the XL, representing an additional 5.

Combining these symbols, XLV represents 45. The use of subtractive notation (placing a smaller numeral before a larger one) is a characteristic feature of Roman numerals. This system allows for a concise representation of various numbers using a limited set of symbols.

In Roman numerals, XL represents 40, and V represents 5. Combining them, XLV represents 45. The Roman numeral system uses specific letters to denote different values, with certain combinations representing specific numbers. In this case, XL (10 less than 50) and V (5) together represent the number 45.
