Question

The set of negative integers ​

Answer 1

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). Zero is not included in either of these sets .

Answer 2

{-1, -2, -3, -4, -5, -6, -7, -8, -9, -10...}

This set is infinite.

Hope it helps!
