The difference between number and numeral is sort of like the difference between a person and his name.You are a person, and there is just one of you.But different people probably call you by different names.In the same way, a number is a thing that we talk about in math, such as "three," which is hard to define exactly. A numeral, on the other hand, is any name or symbol for that number, such as "3" or "III" or "11 (binary)" or whatever animal face is used to represent a three in Mayan carvings... 请看以下地址,或者你在google中搜索number and numeral也能找到 mathforum.org/library/drmath/view/58756.html |
