The absolute value of a number refers to the distance of a number from the origin of a number line. It is represented as |a|, which defines the magnitude of any integer ‘a’. The absolute value of any integer, whether positive or negative, will be the real numbers, regardless of which sign it has. It is represented by two vertical lines |a ...Answer: A complex number is defined as the addition of a real number and an imaginary number. It is represented as “z” and is in the form of (a + ib), where a and b are real numbers and i is an imaginary unit whose value is √ (-1). The real part of the complex number is represented as Re (z), and its imaginary part is represented as Im (z).Jul 25, 2023 · by Jidan / July 25, 2023. Mathematically, set of integer numbers are denoted by blackboard-bold ( ℤ) form of “Z”. And the letter “Z” comes from the German word Zahlen (numbers). Blackboard-bold is a style used to denote various mathematical symbols.

Hilbert's epsilon-calculus used the letter ε ε to denote a value satisfying a predicate. If ϕ(x) ϕ ( x) is any property, then εx. ϕ(x) ε x. ϕ ( x) is a term t t such that ϕ(t) ϕ ( t) is true, if such t t exists.

A bar (also called an overbar) is a horizontal line written above a mathematical symbol to give it some special meaning. If the bar is placed over a single symbol, as in x^_ (voiced "x-bar"), it is sometimes called a macron. If placed over multiple symbols (especially in the context of a radical), it is known as a vinculum. Common uses of the bar symbol include the following. 1. The mean x^_=1 ...Set Symbols.
