Reads like a manual   Someone put a really weird tag on the how it works section on these lines I have removed it  in fact I would very strongly question the whole idea of a tag like this at the very least it needs to be applied with great discretion  articles are never improved by the addition of subjective opinion based on a very highly personal reaction to text that has in fact been hammered out by a number of editors over a considerable period of time In this case one might very well remark what the naughty word expunged do you expect it to read like In Effect  this section IS a manual on how to construct a Roman numeral This is altogether appropriate as this is very probably exactly what the user is looking for Ample space is given to the history of the Roman numerals including the fact that they are very often misspelled and in fact that there is really no immutable standard way of writing them one of their endearing quirks this one might well argue On the other hand there is a usual way of writing them which happens to be fairly logical and consistent and one really needs to give this in some form before one can talk conherently about the exceptions more to come saving this first
