A letter of the alphabet drawn with doubled vertical strokes is called doublestruck, or sometimes blackboard bold (because doublestruck characters provide a means of indicating bold font weight when writing on a blackboard).
R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers.
For example, −37 is a rational number, as is every integer (e.g. 5 = 51). The set of all rational numbers, also referred to as "the rationals", the field of rationals or the field of rational numbers is usually denoted by a boldface Q (or blackboard bold.

\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.
N stands for the set of all natural numbers, and in most definitions, it starts from 1,2,3,..,n. Therefore, it can be assumed that Z+ and N are the same sets since they contain the same elements. Was this answer helpful?
In mathematics, the notation R* represents the two different meanings. In the number system, R* defines the set of all non-zero real numbers, which form the group under the multiplication operation. In functions, R* defines the reflexive-transitive closure of binary relation “R” in the set.
To write text in bold font, use a double asterix or underscores before and after the text.Oct 24, 2016
Z is the set of integers, ie. positive, negative or zero. Z∗ (Z asterisk) is the set of integers except 0 (zero). The set Z is included in sets D, Q, R and C.
In algebra, the letter "m" refers to the slope of a line. The slope of a line determines both its steepness and direction.
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.
