The Roman numeral “MMMDCCXX” represents the number 3720 in standard Hindu-Arabic numerals. Here’s how it breaks down:

- M stands for 1000, so there are three M’s, which is 3 * 1000 = 3000.
- D stands for 500.
- CC stands for 100 + 100, which is 200.
- XX stands for 10 + 10, which is 20.

When you add these values together, you get:

3000 (M) + 500 (D) + 200 (CC) + 20 (XX) = 3720

So, MMMDCCXX in Roman numerals is equivalent to 3720 in standard Arabic numerals.
