Write the successor of:
4,56,309

Answer

To find the successor of the number 456,309, we need to follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Successor**: The successor of a number is the number that comes immediately after it. To find the successor, we simply add 1 to the given number.

2. **Identify the Given Number**: The number we are working with is 456,309.

3. **Add 1 to the Given Number**:
- Start with the last digit of 456,309, which is 9.
- When we add 1 to 9, we get 10. This means we write down 0 and carry over 1 to the next digit.

4. **Handle the Carry**:
- The next digit is 0 (from 456,30**9**). Adding the carry (1) to this digit gives us 0 + 1 = 1. So, we write down 1.
- The next digit is 3. Since there is no carry from the previous addition, we simply write down 3.
- The next digit is 6. Again, there is no carry, so we write down 6.
- The next digit is 5. No carry, so we write down 5.
- The first digit is 4. No carry, so we write down 4.

5. **Combine the Results**: After handling all the digits, we combine them to get the final result.

Thus, the successor of 456,309 is **456,310**.

### Final Answer:
**456,310**
