General Steps for Solving Addition Problems with Regrouping:



1. Align the Numbers: Ensure that the digits are aligned by place value (ones, tens, etc.).
2. Add the Ones Place First: Start by adding the digits in the ones column.
- If the sum is 10 or more, write down the ones digit of the sum and carry over the tens digit to the next column (tens place).
3. Add the Tens Place: Move to the tens column and add the digits, including any carry-over from the ones place.
- If the sum is 10 or more, write down the tens digit of the sum and carry over the hundreds digit to the next column (if applicable).
4. Repeat for Higher Place Values: Continue this process for any higher place values as needed.
5. Write the Final Answer: Combine all the digits to form the final sum.

Example Problem:


Let's solve one of the problems step-by-step:
Problem:
```
6
+ 8
---
```

#### Step-by-Step Solution:
1. Add the Ones Place:
- \( 6 + 8 = 14 \)
- Write down the 4 in the ones place and carry over the 1 to the tens place.

2. Add the Tens Place:
- There are no other digits in the tens place, so just add the carry-over: \( 0 + 0 + 1 = 1 \).

3. Final Answer:
- The sum is \( 14 \).
