18 in roman numerals looks like XVIII
The number 4000 in Roman numerals is represented as "MMMM".
VI (5+1 = 6)
XIX representing, 10 + (10 - 1)
22 = 10 + 10 + 1 + 1 so it is XXII
IVXLCDM No I didn't mistype that. I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1000 The way you use them is a little bit complicated so I won't go into that, but basically, you string them to make numbers like XXV which is 25. The ordering also matters too, but like I said, I won't go into that here.

Arabic(Modern) = 11 Roman = XI Here are the first 20 Roman Numerals 1 = I 2 = II 3 = III 4 = IV ( or IIII on classic dials of clocks). 5 = V 6 = VI 7 = 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 NB The first ;12; numbers you will find on analogue clocks with a classic dial.
21 in Roman numerals is XXI. 1 in Roman numerals is I. 90 in Roman numerals is XC. So, 21 1 90 would be XXI I XC in Roman numerals.
I think you meant 'What does the number one look like in Roman Numerals?' It's like an I. I = 1 II = 2 III = 3 IV = 4 V = 5
