Number System Definition, Types, Conversion, Examples, Facts The former gives the ordering of the set, while the latter gives its size. For finite sets, both ordinal and cardinal number s are identified with the natural numbers. In the infinite case, many ordinal numbers correspond to the same cardinal number. Some number systems that are not included in the complex numbers may be constructed from the real numbers in a way that generalize the construction of the complex numbers. The search for roots of quintic and higher degree equations was an important development, the Abel–Ruffini theorem showed that they could not be solved by radicals . Hence it was necessary to consider the wider set of algebraic numbers . Ordinal numbers tell the position of an object rather than its quantity. The numbers that we use for counting are called cardinal numbers. As the name suggests, these are numbers written in words. This number system using 10 digits is called the Decimal Number System.
