What math did Roman engineers use?

How did the Roman use mathematics?

Although they made virtually no contributions to theoretical mathematics, the ancient Romans used applied mathematics in surveying, structural engineering, mechanical engineering, bookkeeping, creation of lunar and solar calendars, and even arts and crafts.

What do the Roman numerals stand for?

In the Roman numeral system, the symbols I, V, X, L, C, D, and M stand respectively for 1, 5, 10, 50, 100, 500, and 1,000 in the Hindu-Arabic numeral system. A symbol placed after another of equal or greater value adds its value.
