[roman-numerals] Tidy up grammer and formatting.

Line 13 appears as an aside related to line 12 so I'd remove the period from line 12 and keep notice lowercase.

That'd look like this then.

"The Romans wrote numbers using letters - I, V, X, L, C, D, M (notice these letters have lots of straight lines and are hence easy to hack into stone tablets)."

That suggested fix applies to any other asides bracketed by parentheses.

[IsaacG]

This would mean removing the . from the end of line 12 and moving it to the end of line 13? And joining the two lines.

[IsaacG]

If it's one sentence, should it be:

The Romans wrote numbers using letters - I, V, X, L, C, D, M; notice these letters have lots of straight lines and are hence easy to hack into stone tablets.

[BNAndras]

That works too. They're both complete sentences so there's no reason they can't be joined with a semi-colon. As an aside, it's longer than the rest of the sentence so it looks a little weird in my original suggestion.

[IsaacG]

Was your original sentence to keep them as separate sentences? I thought removing the period meant making them one sentence.

[BNAndras]

I made them one sentence with the intention to keep the original second sentence the aside I thought it was. Your version flows better though with the semi-colon and no parentheses.

[BNAndras]

I'd remove this line. Romans did and could go higher using alternatives forms of notation. https://mathworld.wolfram.com/RomanNumerals.html

I like it! @iHiD next up: splitting this into an instructions and introduction document?
