What are the basic Roman numeral symbols?
I = 1, V = 5, X = 10, L = 50, C = 100, D = 500 and M = 1000. Other numbers combine these: 2026 is MMXXVI.
Why is 4 written as IV and not IIII?
Roman numerals use subtraction: a smaller symbol before a larger one is subtracted. So IV is 5 − 1 = 4 and IX is 10 − 1 = 9. (Clock faces sometimes still use IIII by tradition.)
When do children learn Roman numerals in India?
Most boards introduce Roman numerals I to XX in Class 3 or 4, extending to larger values in Class 5.
