It looks like you're asking about addition. Here's a quick overview of **addition**:

### What is Addition?
Addition is one of the basic arithmetic operations where two or more numbers are combined to get a **sum**. For example:

\[
3 + 4 = 7
\]

Here, 3 and 4 are called **addends**, and 7 is the **sum**.

### Rules for Addition:
1. **Commutative Property**: Changing the order of numbers doesn't affect the sum:
   \[
   a + b = b + a
   \]
2. **Associative Property**: Grouping numbers in different ways doesn't affect the sum:
   \[
   (a + b) + c = a + (b + c)
   \]
3. **Additive Identity**: Adding 0 to any number doesn't change the number:
   \[
   a + 0 = a
   \]

### Example:
\[
23 + 57 = 80
\]

Here are some questions to consider:
1. How is addition used in solving algebraic equations?
2. What is the difference between addition and subtraction?
3. Can you explain how the commutative property works in real-life situations?
4. What are some mental math tricks for addition?
5. How does addition of fractions work?

**Tip**: Adding in columns (starting from the right) makes it easier to add larger numbers.
