what's an integer?

Answer 1

An integer is basically a whole number but it can be negative also.

Answer 2

An integer is one of the numbers ... -3 , -2 , -1 , 0 , 1 , 2 , 3 , 4 , ... .
In both direction there are infinitely much.
If n is an integer, then n+1 and n-1 are integers as well.
So no fractions.

Answer 3

The integers consist of the positive natural numbers (1, 2, 3, …), their negatives (−1, −2, −3, ...) and the number zero. A formal way of stating this: the integers are the only integral domain whose positive elements are well-ordered, and which has order preserved under addition. Like the natural numbers, the integers form a countably infinite set. The set of all integers is usually denoted in mathematics by a boldface Z (or blackboard bold, ), which stands for Zahlen (German for "numbers").

The term rational integer is used, in algebraic number theory, to distinguish these 'ordinary' integers, in the rational numbers, from other concepts such as the Gaussian integers.

Answer 5

What An Integer

Answer 6

numbers that don't have a decimal part
(0, 1, 2, 3 ...) are integers. negative numbers like (-1, -2, -3...) are also integers, while 1.25 it is not an integer

Answer 7

The integers consist of the positive natural numbers (1, 2, 3, …), their negatives (−1, −2, −3, ...) and the number zero. A formal way of stating this: the integers are the only integral domain whose positive elements are well-ordered, and which has order preserved under addition. Like the natural numbers, the integers form a countably infinite set. The set of all integers is usually denoted in mathematics by Z
Z = {.........,-3,-2,-1,0,1,2,3,............}

Answer 8

An integer is a whole number. So something that isn't a fraction or has a decimal point in it.
