Answer 1

Answer:

An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. ... In fact, (rational) integers are algebraic integers that are also rational numbers.
