Total148CXLVIII

CXLVIII is written one place at a time, from the largest to the smallest: C (100) + XL (40) + VIII (8) = 148.

XL is the only subtraction: the X before the L takes away 10, so XL = 40.

Common mistakes

Wrong: CXXXXVIII

Why isn't 148 written as CXXXXVIII?

A symbol can't be repeated four times in a row. 40 is XL (50 − 10), not XXXX, so 148 is CXLVIII.

Wrong: CXLIIX

Why isn't 148 written as CXLIIX?

Only one smaller symbol can stand before a larger one, so IIX doesn't work. 8 is VIII (5 + 3), so 148 is CXLVIII.
