The Rules for Writing Roman Numerals
Don’t repeat a letter more than three times in a row.
So 4 is written not as IIII but as IV (one before five).
And 6 would be written as VI (one after five).

Let’s have a go…1 = I2 = II3 = III4 = IV5 = V6 = VI7 = VII
• 8 = VIII• 9 = IX• 10 = X• 11 = XI• 12 = XII• 13 = XIII• 14 = XIV
• 15 = XV• 16 = XVI• 17 = XVII• 18 = XVIII• 19 = XIX• 20 = XX• 21 = XXI
