Heya✌️☺️♥️

Step-by-step explanation:

✏️Integers. The set of integers is represented by the letter Z. An integer is any number in the infinite set, ... Z+ is the set of all positive integers (1, 2, 3, ...), while Z- is the set of all negative integers (..., -3, -2, -1).

ADDITIONAL INFORMATION:-

✏️German mathematicians contributed a great deal in number theory. Number theory tends to focus on integers. The notation Z came from the first letter of the German word Zahl, which means number. The German terminology for integer numbers specifically is ganze Zahlen, which literally means whole numbers, and is the source for common, somewhat relatively informal usage by English-speaking mathematicians of whole number as a synonym for integer.

✒️Hope it helps ✌️☺️♥️...
