In the United States, the T-bone has the meat-cutting classification IMPS 1174; the porterhouse is IMPS 1173. In British usage, followed in Commonwealth countries, porterhouse refers to the strip steak side of a T-bone steak, while the tenderloin side is called the fillet.
In set theory, an ordinal number, or ordinal, is one generalization of the concept of a natural number that is used to describe a way to arrange a collection of objects in order, one after another. Any finite collection of objects can be put in order just by the process of counting: labeling the objects with distinct whole numbers.
Key Difference: Cardinal is used to count or indicate how many. Ordinal numbers are words that represent rank and order in a set. Nominal numbers are basically number that are used to identify something. The terms cardinal, ordinal and nominal are common terms that are used in statistics or general mathematics. The terms are used to classify numbers in a category to make it easier for use. These are often confusing for many people, but once understood it is quite simple in order to understand.
