Subtraction Square

The properties of addition and the proof of the sum are fundamental concepts in arithmetic. Here are some key properties of addition:

1. **Commutativity**: For all real numbers a and b, a + b = b + a. This means you can add numbers in any order, and the result remains the same.

2. **Associativity**: (a + b) + c = a + (b + c). This property states that when you add more than two numbers, the grouping doesn’t matter as long as you perform the operations step by step.

3. **Identity Property**: There exists an additive identity, 0, such that for any real number a, a + 0 = a. This means adding zero to any number does not change its value.

4. **Inverse Property**: For every real number a, there’s an additive inverse (-a) such that a + (-a) = 0. This is the concept of negative numbers, where adding their opposites results in zero.

5. **Closure**: The sum of any two real numbers is also a real number. The set of real numbers is closed under addition.

To prove these properties, typically one uses algebraic manipulation and the definition of addition. For example, to prove commutativity, you can write out the left-hand side and the right-hand side and show that they are equal using the distributive property and the definition of equality.

Proofs of these properties can be found in textbooks on algebra or pre-algebra, such as “Elementary Algebra” by Michael Sullivan or “Abstract Algebra” by David S. Dummit and Richard M. Foote. These books provide detailed explanations and examples for each property.

The sum of 100 and 500 is 600.
