What does Z stand for math
Integers
Integers. The letter (Z) is the symbol used to represent integers. An integer can be 0, a positive number to infinity, or a negative number to negative infinity.
Why Z is the symbol of integers
The notation Z for the set of integers comes from the German word Zahlen, which means "numbers". Integers strictly larger than zero are positive integers and integers strictly less than zero are negative integers.
What is the R in math
The set of real numbers
The set of real numbers is denoted R or. and is sometimes called "the reals". The adjective real, used in the 17th century by René Descartes, distinguishes real numbers from imaginary numbers such as the square roots of −1. The real numbers include the rational numbers, such as the integer −5 and the fraction 4 / 3.

Is the integer symbol Z or I
An integer is any number in the set { …, -3, -2, -1, 0, 1, 2, 3, … }. The symbol representing the integers is I. The integers are composed of positive whole numbers, the additive inverses of the whole numbers and zero. I: { …, -3, -2, -1, 0, 1, 2, 3, … }
What is Z in number theory
Z denotes the set of integers; i.e. {…,−2,−1,0,1,2,…}. Q denotes the set of rational numbers (the set of all possible fractions, including the integers). R denotes the set of real numbers. C denotes the set of complex numbers. (This set will be introduced more formally later.)
What is R vs Z in math
Special sets
N denotes the set of natural numbers; i.e. {1,2,3,…}. Z denotes the set of integers; i.e. {…,−2,−1,0,1,2,…}. Q denotes the set of rational numbers (the set of all possible fractions, including the integers). R denotes the set of real numbers.
What does ∈ R mean in math
x is a real number
x ∈ R just means that x is a real number (can be any number, fraction, decimal, whole, positive, negative) x ∈ Z means that x is an integar (a positive or negatie whole number e.g. -2,0, 9, -32 etc) At the end of a question it is really just there to give you a way to check if your answer is correct, if it said x ∈ Z …

What is Z * complex numbers
The conjugate of a complex number z is denoted by z̅ or z*. If z = a + ib is a complex number, where a is the real part and ib is the imaginary part, then its conjugate is z* or z̅ = a – ib. In an argand plane, the complex conjugate (a – ib) is the mirror image of the complex number (a + ib) about the real axis.
Why is 1000 called 1K
