An integer is a type of number in mathematics. It is a whole number that can be positive, negative, or zero. It does not have any fractional or decimal parts. Examples of integers are -3, 0, 5, and 10.

To understand what an integer is, you can start by knowing the basic concepts of numbers. Whole numbers are the set of numbers that include zero and all positive numbers (0, 1, 2, 3, ...). Integers, on the other hand, include negative numbers as well.

One way to remember the concept of integers is by visualizing a number line. Imagine a horizontal line where zero is at the center. The numbers on the right side of zero are positive integers, and the numbers on the left side of zero are negative integers.

To determine if a number is an integer, you would look at whether it has any decimal or fractional components. If the number does not have any decimal or fractional parts, it is an integer.
