Integers are whole numbers that can be positive, negative, or zero. They include numbers like -5, 0, 1, 5, and do not have decimal or fractional parts. The set of all integers is represented by Z and includes positive numbers greater than zero, negative numbers less than zero, and zero, which is neither positive nor negative but is a whole number. Examples of integers are any numbers in the set Z, such as -5, 0, 1, 5, 8, 97, and 3,043.

2. INTEGERS
is a whole number from the set of
negative, non-negative, positive, and
0 numbers
an integer is a number with no decimal or
fractional part and it includes negative
and positive numbers, including zero.

3. A set of integers, which is represented
as Z, includes:
Positive Numbers: A number is
positive if it is greater than zero.
Example: 1, 2, 3, 4 . . .
INTEGERS

4. Negative Numbers: A number is
negative if it is less than zero.
Example: -1, -2, -3, -4 . . .
Zero is defined as neither a negative
number nor a positive number. It is a
whole number.

5. Z = {… -7, -6, -5, -4, -3, -2, -1, 0, 1,
2, 3, …}
A few examples of integers are: -5, 0,
1, 5, 8, 97, and 3,043.
