What is an integer

Answer 1

integers are whole numbers, but either positive or negative

natural numbers are just positive integers

whole numbers are natural numbers, plus zero, but no negative integers

An integer is a number that does not have any proper fraction or any numbers to the right of the decimal point, other than zero

A rational number is a fraction a/b, where both a and b are integers. IF that's not possible, the number is irrational.

An integer is equivalent to an improper fraction, a/b where b divides a evenly with no remainder. 4/2, 9/3 6/6

4.2/2.1, (7/9)/(3.5/9) ....

Integers are called all whole numbers such as 0, -1, 1, -2, 2, -3, 3, -4, 4, ..., -10, 10, -11, 11, -12, 12 etc.
