Probably he figured that you already knew them from your daily life. I learned mine from my math book; I hate the thing, but it's a good book. <br /><br />I is one; II is two, and III is three. V is five, and IV (one less than five) is four. VI (one more than five) is six, VII is seven, and VIII is eight. X is ten; IX (one less than ten) is nine. XI is eleven. L is fifty; XL is ten less than fifty, or forty, and LX is ten more than fifty, or sixty. So, XXXIV is thirty-four; LXXII is seventy-two, and so on. LXXX is eighty, C is one hundred, and XC is ninety. It's quite complicated at times, but you'll want to learn, I'm sure, since you love Latin so much.
