Which Roman numeral represents the number 5?

In the Roman numeral system, each numeral has a specific value. The numeral V represents the value of 5. This is based on the historical use of Roman numerals, where specific letters were used to denote certain quantities.

The letter I represents 1, while X signifies 10 and C signifies 100. Each of these numerals has its own distinct value, which does not overlap with that of V. Therefore, V is specifically and unequivocally recognized as the Roman numeral for 5. Understanding the foundation of Roman numerals aids in recognizing their values accurately.
