What does XL stand for in roman numerals?

Answer 1

In Roman numerals, M = 1000, D = 500, C = 100, L = 50, X = 10, V = 5, and I = 1. A single Roman numeral of lesser value placed before a Roman numeral of higher value means to subtract the lesser one.

So, XL means 50 - 10 = 40.

Answer 2

In Roman numerals XL means 50-10 = 40
