1. Script P stands for power sets but P(n) normally stands for the space of polynomials of order n.Aug 2, 2020
R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers.
Important sets in mathematics are commonly denoted using doublestruck characters, e.g., C for the set of complex numbers, Q for the rational numbers, R for the real numbers, for Euclidean n-space, and Z for the integers.
2. the bb in \mathbb stands for "blackboard bold". the \math indicates that this is a font/symbol to be used only in math.Aug 7, 2015
Z+ is the set of all positive integers (1, 2, 3, ...), while Z- is the set of all negative integers (..., -3, -2, -1). Zero is not included in either of these sets .
Real numbers are, in fact, pretty much any number that you can think of. This can include whole numbers or integers, fractions, rational numbers and irrational numbers. Real numbers can be positive or negative, and include the number zero.Jan 15, 2014
U+2124. ℤ Represents the set of integers. (The Z is for Zahlen, German for "numbers", and zählen, German for "to count".)
The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value "5" is the Y Coordinate. Also called "Ordinate"
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.
It's usually , meaning the finite field with elements. The letter is used because the number of elements in a finite field is always a power of a prime, commonly denoted . For example, there's a field with elements and a field with , but there's no field .
\mathbb command is used to turn on blackboard-bold for uppercase letters and lowercase 'k'. If lowercase blackboard-bold letters are not available, then they are typeset in a roman font.
Noto Sans Math is a font that contains symbols for mathematical notation.
