Did it again... If you don't know what are those letters in the thumbnail or numberlings if you're new, those are Roman Numerals. I'll show you an example: I = 1 II = 2 III = 3 IV = 4 V = 5 VI = 6 VII = 7 VIII = 8 IX = 9 X = 10 XI = 11 XII = 12 XIII = 13 XIV = 14 XV = 15 XVI = 16 XVII = 17 XVIII = 18 XIX = 19 XX = 20 L = 50 C = 100 D = 500 M = 1000 and that's it.
