Or you can say integers are Combination of opposite of whole numbers and whole numbers. 

Integers donot include fraction numbers or decimal numbers.

• Whole numbers and  their negative numbers are termed as integers.

Types of Integers

We classify integers into three categories

1) Negative Integers

2) zero

3) Positive Integers

1)  Negative Integers 

        All integers less than 0 are known as negative integers.

         Negative Integers have - (minus) sign written on left of numbers

        Example. -4,-3, etc.

         These integers are less than positive integers.

2) zero

    Zero is the counting number which is included in integers.

 Zero is neither negative Integers nor positive integer.

3) Positive Integers

      All integers greater than zero are known as positive integers.

      These integers donot take any sign with them, as a number with

     no sign in mathematics  is termed as a positive integer.

     Example. 1,2,3,4, etc.
