What does Z+ mean in math?
Integers. The set of integers is represented by the letter Z. An integer is any number in the infinite set, Integers are sometimes split into 3 subsets, Z+, Z- and 0. Z+ is the set of all positive integers (1, 2, 3.), while Z- is the set of all negative integers (…, -3, -2, -1).
Is 0 in the set 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 .
