“数字”与“数”是两个既有联系又有区别的数学概念.“数字”即阿拉伯数字,又称“数码”,只有十个:0,1,2,3,4,5,6,7,8,9.而用这十个“数字”却可组成无穷多个“数”来.一些媒体在宣传报道中常犯这样的错误:把一个“很大的数”说成是一个“很大的数字”,甚至称之为“天文数字” “Number” and “number” are two mathematical concepts that are both connected and distinct. “Number” is the Arabic numeral, also known as “number”, of which only ten are: 0,1,2,3,4,5,6 , 7, 8, and 9. The use of these ten “numbers” can constitute an infinite number of “numbers.” Some media often make such mistakes in their propaganda stories: a “great number” is said to be a “ Big number ”or even called“ astronomical number ”
