MMMCMXL

MMMCMXL is a Roman numeral representing 3,940. It is composed of MMM (3,000) + CM (900) + XL (40). The CM and XL are examples of subtractive notation, where a smaller value placed before a larger value indicates subtraction.

In the standard system used for numbers from 1 to 3,999, MMMCMXL is a valid form. Its value can be verified by summing the components: 3,000 + 900 + 40 = 3,940. To represent 4,000 or more, other conventions are used (for example, using an overline to multiply a numeral by 1,000), while simply writing MMMM is not considered standard for 4,000.

Historically, Romans varied in their use of large-number notation, and the modern long-form subtractive notation has been developed to simplify interpretation. In contemporary contexts, MMMCMXL may appear in educational materials, historical chronologies, or as an example of Roman numeral syntax.
