Note that in American English, many students are taught not to use the word and anywhere in the whole part of a number, so it is not used before the tens and ones. It is instead used as a verbal delimiter when dealing with compound numbers. Thus, instead of "three hundred and seventy-three", one would say "three hundred seventy-three". For details, see American and British English differences. & y/ W$ @- \7 W3 I1 ?6 B; y, l; A" k7 D0 B) Y4 M/ F

数字16, 古代说法就是 fourt night and two. 因为fourt night 实际上是fourteen, teen这个词是evening而来。所以14 ...9 I# Z( p* I( `2 p
