Cardinality of countable ordinal numbers set. A data set does not necessarily have to have only one mode - if two or more values are tied for being the most common the set can be said to be bimodal or multimodal respectively - in other words all of the most-common values are the sets modes. Complex numbers such as 23i have the form z x iy where x and y are real numbers.

We use the symbol as a short-hand way of referring to the values in the set. We write A B C Basically we find A B C by putting all the elements of A B and C together. The null set is a principle component of mathematics as it serves as a zero in both set theory and number theory.
