When we read a numeral out loud, we say the number word for that numeral. When we want to write a number, we can write the numeral or the word. For example, we say the word five and write the numeral 5 or the word five. The number is the idea we think of when we see the numeral or when we see or hear the word. There are several kinds of numbers.
Ordinal numbers tell the position of something in an ordered set.
