Question: Hi, I would really like to know what an interger is!... This is the question I have... True or False? -1207 in an interger? Could you please answer that question, and explain why you chose that answer? thanks in advance.

in our lessons, i have learned that an integer is any real numbers..it is neither a positive or a negative integer..but 0 is excluded because it is neither positive nor negative..then, 1 up to infinity is a positive integer while -1 down to infinity is a negative integer..-1207 is an integer.. The integers (from the Latin integer, literally "untouched", hence "whole": the word entire comes from the same origin, but via French[1]) are the set of numbers consisting of the natural numbers including 0 (0, 1, 2, 3, ...) and their negatives (0, −1, −2, −3, ...). They are numbers that can be written without a fractional or decimal component, and fall within the set {... −2, −1, 0, 1, 2, ...}. For example, 65, 7, and −756 are integers; 1.6 and 1½ are not integers. In other terms, integers are the numbers one can count with items such as apples or fingers, and their negatives, including 0. More formally, the integers are the only integral domain whose positive elements are well-ordered, and in which order is preserved by addition. Like the natural numbers, the integers form a countably infinite set. The set of all integers is often denoted by a boldface Z (or blackboard bold , Unicode U+2124 ℤ), which stands for Zahlen (German for numbers, pronounced "tsAH-len").[2] In algebraic number theory, these commonly understood integers, embedded in the field of rational numbers, are referred to as rational integers to distinguish them from the more broadly defined algebraic integers.

An integer is: A positive or negative whole number or zero. A number without a decimal (0, 1, 25, 173, 1032, etc.). So yes, -1207 can be classified as an integer.

-1207 is an integer..They are numbers that fall within the set {... −2, −1, 0, 1, 2, ...}, those with no decimal points.

One way to describe a set of numbers is to do it relative to other number sets: Number groups you learn in 1st grade: numbers with no fractional parts (values after the decimal) Counting numbers: 1,2,3,4,5,6, ... Whole numbers: 0,1,2,3,4,5,6, ... (Whole numbers are the sequence of Zero followed by the Counting numbers) Integers: ..., -2,-1,0,1,2, ... (Integers are the set of whole numbers preceded by the set of counting numbers reflected about zero.) Number groups you learn in 2nd grade: numbers with fractional parts (values after the decimal) Rational numbers: numbers which can be written as the ratio of two integers. Irrational numbers: numbers which cannot be written as the ratio of two integers. Real numbers: The set of all rational and irrational numbers, including zero. Functionally, this is also "the subset of complex numbers having zero imaginary part" (but that definition introduces some circular logic.) Number groups you learn in 3rd grade: introduced after the basic notions of addition, subtraction, multiplication and division have been mastered and the notion of square and square root have been established. Complex numbers: The set of numbers of the form (a + b i) where a,b are real numbers and i = sqrt(-1). Given this taxonomy of numbers, an integer can be succinctly described as the subset of complex numbers having zero imaginary part, and no fractional part. As a result, -1207 is clearly an integer.
