Answer

XLVI

Answer

Question 2

Sam tried to write the number 70 as "L0X". Which answer best explains why this is not a correct Roman numeral?

Accepted Answer

Roman numerals have no symbol for zero, so the zero cannot be used; the correct way to write 70 is LXX.

Answer

Roman numerals use a zero just like Arabic numbers, so L0X would be read as 70.

Answer

The zero should be placed after the X, so the numeral should be LX0.

Answer

Roman numerals have a special zero sign called N, so the correct form would be LNX.
