Cardinal, Ordinal and Nominal Numbers
Cardinal Numbers
A Cardinal Number says how many of something there are, such as one, two, three, four, five.
A Cardinal Number answers the question "How Many?"
It does not have fractions or decimals, it is only used for counting.
How to remember: "Cardinal is Counting"
Ordinal Numbers
An Ordinal Number tells us the position of something in a list.
1st, 2nd, 3rd, 4th, 5th and so on (seeCardinal and Ordinal Numbers Chart for more.)
How to remember: "Ordinal says what Order things are in".
Nominal Numbers
A Nominal Number is a number used only as a name, or to identify something (not as an actual value or position)
How to remember: "Nominal is a Name".
