## What does Z symbol mean?

The doublestruck capital letter Z,, denotes the ring of integers,,, 0, 1, 2,. The symbol derives from the German word Zahl, meaning “number” (Dummit and Foote 1998, p. 1), and first appeared in Bourbaki’s Algèbre (reprinted as Bourbaki 1998, p. 671).

## What is Z in 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. C denotes the set of complex numbers.

Z means “Zero”.

## Is 0 included in Z+?

Integers. The set of integers is represented by the letter Z. 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.

## Is Z+ the same as N?

Z stands for Zahlen, which in German means numbers. When putting a + sign at the top, it means only the positive whole numbers, starting from 1, then 2 and so on. N is a little bit more complicated set. It stands for the natural numbers, and in some definitions, it starts from 0, then 1 and so on.
