Question

4. Show that each of the following is meaningless. Give reason in each case.
(1) VC
(11) IL
(111) VVII
(iv) IXX
Hint. (U V is never subtracted.
(10 I can be subtracted from V and X only.
(0) V. L. D are never repeated,
(iv) IX cannot occur to the left of X​

Answer 1

1) VC cannot be written as V V,L and D are never subtracted
2) IL as L must be placed before L which will give us 51 and 49 can be written as XLIX
3) VVII V can never be repeated we can write 12 as XII
4) as IV= 4 and IX=9
5) V L D are never repeated and subtracted as 5+5 can be written as X, 50+50 as C , 500+500 as M
As we cannot subtract 9 from 10 we can simply write 1 as I
