The sets of rational and irrational numbers together make up the set of real numbers.As we saw with integers, the real numbers can be divided into three subsets: negative real numbers, zero, and positive real numbers.Number systems. Each number system can be defined as a set. There are several special sets of numbers: natural, integers, real, rational, irrational, and ordinal numbers.These sets are named with standard symbols that are used in maths and other maths-based subjects. For example, mathematicians would recognise Z to define the set of all integers. WikipediaInterval notation is a way to describe continuous sets of real numbers by the numbers that bound them. Intervals, when written, look somewhat like ordered pairs. However, they are not meant to denote a specific point.

The pi symbol is a mathematical constant which is defined as the ratio of circumference of a …Unit Imaginary Number. The square root of minus one √ (−1) is the "unit" Imaginary Number, the equivalent of 1 for Real Numbers. In mathematics the symbol for √ (−1) is i for imaginary. But in electronics the symbol is j, because i is used for current, and j is next in the alphabet.

Finally, the set of real numbers 11, denoted \(\mathbb{R}\), is defined as the set of all rational numbers combined with the set of all irrational numbers.
