**Definition:**Whole numbers are the set of numbers that includes all the positive integers from 0 upwards.**Examples:**Some examples of whole numbers are 0, 1, 2, 3, 4, 5, 6, and so on.**Properties:**- Whole numbers are closed under addition and multiplication, meaning that when you add or multiply two whole numbers, the result is also a whole number.
- Whole numbers are not closed under subtraction or division. For example, 5 - 7 is not a whole number, and 7 ÷ 3 is not a whole number.
- The whole number 0 is the additive identity, meaning that adding 0 to any whole number gives the same whole number.

**Number Line:**Whole numbers can be represented on a number line, with 0 as the starting point and the numbers increasing to the right.**Operations:****Addition:**When adding whole numbers, simply add the digits together. Carry over any digits if the sum is greater than 9.**Subtraction:**When subtracting whole numbers, borrow from the next highest place value if necessary. If the top number is smaller than the bottom, subtracting will result in a negative number, which is not a whole number.**Multiplication:**To multiply whole numbers, simply multiply the digits together. The result will also be a whole number.**Division:**Division of whole numbers may result in a quotient with a remainder, which is not a whole number. However, if the division is exact, the quotient will be a whole number.

**Real-Life Applications:**Whole numbers are used in everyday life for counting objects, representing quantities, and performing basic arithmetic operations.
