Answer 2

I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV, XVI, XVII, XVIII, IXX, XX, XXI, XXII, XXIII, XXIV, XXV, XXVI, XXVII, XXVIII, XXIX, XXX. These are the numbers 1-30. The roman numbers are written with letters I, V, X, L, C, D and M. The letters before bigger numbers are subtracted from the bigger number. For example, the number 90 is written XC, because X means 10, and C means 100. That's 100-10.
