General Approach to Adding Three-Digit Numbers

To add two three-digit numbers, follow these steps:

1. Align the numbers by place value:
- Ensure that the ones, tens, and hundreds places are aligned vertically.

2. Add column by column from right to left:
- Start with the ones place.
- Move to the tens place.
- Finally, add the hundreds place.

3. Carry over if necessary:
- If the sum in any column is 10 or more, carry the extra digit to the next column to the left.

4. Write the final answer:
- Combine the results from each column to get the total sum.

Example Problem

Let’s solve one of the problems from the worksheet as an example:
```
434
+ 237
------
```

#### Step-by-Step Solution:
1. Align the numbers:
```
434
+237
------
```

2. Add the ones place:
- \( 4 + 7 = 11 \)
- Write down 1 and carry over 1 to the tens place.
```
434
+237
------
1
```

3. Add the tens place (including the carry-over):
- \( 3 + 3 + 1 (\text{carry-over}) = 7 \)
- Write down 7.
```
434
+237
------
71
```

4. Add the hundreds place:
- \( 4 + 2 = 6 \)
- Write down 6.
```
434
+237
------
671
```

5. Final Answer:
```
434
+237
------
671
```

So, \( 434 + 237 = 671 \).

How to Solve the Entire Worksheet

You can apply the same method to all the problems on the worksheet. Here’s a quick breakdown of how to approach it efficiently:

1. Work systematically: Solve one problem at a time, moving from left to right.
2. Check your work: Double-check each column to ensure no mistakes in addition or carrying.
3. Use scratch paper if needed: For complex sums, it helps to write out the intermediate steps.
