The numbers that describe the positions of objects are known as ordinal numbers. Children learn to count from one to ten very quickly, and maybe they know the numbers from twenty-one to thirty also.

These phrases all refer to ordinal numbers examples. While the counting numbers, such as 0, 1, 2, 3, 4, and 5, are known as cardinal numbers.
