What Are Integers?

• Integers can be defined as the set of all Whole Numbers and the negatives of Natural Numbers.
• In simple language, all the numbers from -∞ to +∞ (∞ means infinity) are Integers.
• The numbers greater than 0 are called positive integers and the numbers less than 0 are called negative integers.
• ‘0’ (Zero) is neither a positive integer nor a negative integer. It is a Neutral Integer.
• Integers DO NOT include decimals and fractions.
• On a number line, the positive integers are indicated on the right side of zero and negative integers are indicated on the left side of zero.
• Integers are denoted by letter ‘Z’.
