What number is IIIV?

Answer 1

V + III

Answer 2

That's hard to say. In Roman numerals I=1 and V=5. However, putting a I before a V would actually mean 4... only after the V would it add to it. No Roman numerals are written this way. If it were VIII, then it would be 8. This just looks like a mistake... but I suppose it is possible that someone meant it to be 2 (actual way to write that would be II), or to be 8, but someone wrote it backwards.

There is no IIIV. VIII stands for eight (8). The Roman Numeral system is based on the abacus. There cannot be three beads to the left of a Five Bead (V). One bead to the left of the V makes four (4).
