What is the value of LC in roman numerals?

Answer 1

150

In the opinion of another contributor:

In Roman numerals LC = 50 because LC = -50+100 = 50

But in Roman numerals CL = 150 because CL = +100+50 = 150

Answer LC is an incorrect way of writing 50, why would you write 50 less than 100 when you could simply write L (50)?

Aditional input:

The rule of subtraction isn't used, except between I's and X's. E.g, you wouldn't write IL for 49, rather this should be written as forty (XL) and nine (IX), or XLIX.

Therefore LC doesn't make sense, or is 150.
