Properties of Addition?
There are four properties of addition of whole numbers.
Closure Property
Commutative Property
Associative Property
Additive Identity Property
Whole numbers
Natural numbers (Counting numbers), including 0, form the set of whole numbers.
Closure Property:
The sum of the addition of two or more whole numbers is always a whole number.
Whole Number + Whole Number = Whole Number
For example, 2 + 4 = 6
Commutative Property
When we add two or more whole numbers, their sum is the same regardless of the order of the addends.
Example 1: 2 + 4 = 4 + 2 = 6
Associative Property
When three or more numbers are added, the sum is the same regardless of the grouping of the addends.
For example (4 + 2) + 3 = (4 + 3) + 2
Here, the addends are 2, 4 and 3. So, as per the associative property, the sum of the three numbers will remain the same, no matter how we group them.
Additive Identity Property
On adding zero to any number, the sum remains the original number. Adding 0 to a number does not change the value of the number.
For example, 3 + 0 = 3
