At least in Greek, English, French, Catalan and Spanish, the numbers 11 and 12 (and in the Latin ones, all the way up to 15) have special names. As far as I know this is the case of all Latin languages. Is it not so in your native tongue? Do you know of any language where the same rule makes the word for 11 and for 31?
