I dont want to ask anything code related, but I just want to ask about the logic behind the conversion.
I looked it up online and they said there is a rule of subtraction.
1 2 3 4 5 translate to roman numeric is: I II III IV V
and noticed that 4 is
IV which is literally V minus I.
So we put the bigger number at second and the smaller number up front.
Then we do subtraction.
So I have a question then… when do we need to apply this rule of subtraction then??
Let’s say, I have a number 98, I can see it as : 100-10+8 or I can see it as 40+50+8.
So when do I know I need to use the 1st method and vise versa, when do I know to use the second method?
(and the second method is wrong btw…)
