Addition
Addition is one of the four basic arithmetic operations. It combines two or more numbers to find their total or sum. Addition is commutative, meaning the order of numbers doesn't affect the result.
Addition Properties
- Commutative Property: a + b = b + a
- Associative Property: (a + b) + c = a + (b + c)
- Identity Property: a + 0 = a
- Closure Property: The sum of any two real numbers is a real number

Frequently Asked Questions
How do you add multiple numbers?
To add multiple numbers, simply add them one by one from left to right. The addition operation is commutative, meaning the order doesn't affect the result.
What is the commutative property of addition?
The commutative property states that changing the order of addends does not change the sum. For example, 3 + 5 = 5 + 3 = 8.
How do you add decimal numbers?
To add decimal numbers, align the decimal points and add as usual. The decimal point in the sum should be directly below the decimal points in the addends.
