3 Digit Addition with Regrouping Worksheet

The task involves solving 3-digit addition problems with regrouping. Regrouping (also known as carrying) is the process of transferring a digit from one column to another during addition when the sum in a column exceeds 9.

Let's solve one of the problems step by step as an example, and then I'll summarize the solutions for all the problems.

Example Problem: \( 466 + 273 \)

1. Align the numbers by place value:
```
466
+ 273
```

2. Add the ones place:
- \( 6 + 3 = 9 \)
- Write down 9.

3. Add the tens place:
- \( 6 + 7 = 13 \)
- Write down 3 and carry over 1 to the hundreds place.

4. Add the hundreds place:
- \( 4 + 2 + 1 \) (carried over) \( = 7 \)
- Write down 7.

5. Final answer:
```
466
+ 273
------
739
```

Solutions for All Problems

Here are the solutions for all the problems in the image:

15. \( 351 + 148 = 499 \)
16. \( 167 + 132 = 299 \)
17. \( 252 + 467 = 719 \)
18. \( 474 + 375 = 849 \)
19. \( 323 + 177 = 500 \)
20. \( 375 + 275 = 650 \)
21. \( 488 + 101 = 589 \)
22. \( 404 + 153 = 557 \)
