Number [SEP] Main classification
Numbers can be classified into sets, called number systems, such as the natural numbers and the real numbers. The major categories of numbers are as follows: There is generally no problem in identifying each number system with a proper subset of the next one (by abuse of notation), because each of these number systems is canonically isomorphic to a proper subset of the next one. The resulting hierarchy allows, for example, to talk, formally correctly, about real numbers that are rational numbers, and is expressed symbolically by writing
