Based on the image provided, I have solved all the triple-digit addition and subtraction problems presented on the worksheet. Since the worksheet is titled "Without Regrouping," each problem was solved by adding or subtracting the digits in each place value (hundreds, tens, ones) independently.
Here are the solutions for all the problems:
Left Worksheet:
*
Row 1:
* 460 - 320 = 140
* 593 + 904 = 1497
* 217 + 221 = 438
* 717 - 614 = 103
*
Row 2:
* 310 + 242 = 552
* 386 - 112 = 274
* 350 - 200 = 150
* 233 + 542 = 775
*
Row 3:
* 366 - 161 = 205
* 241 + 342 = 583
* 214 - 102 = 112
* 311 + 484 = 795
*
Row 4:
* 134 + 101 = 235
* 113 + 222 = 335
* 859 - 742 = 117
* 999 - 444 = 555
Right Worksheet:
The right worksheet contains the exact same set of problems as the left worksheet. Therefore, the solutions are identical.
*
Row 1:
* 460 - 320 = 140
* 593 + 904 = 1497
* 217 + 221 = 438
* 717 - 614 = 103
*
Row 2:
* 310 + 242 = 552
* 386 - 112 = 274
* 350 - 200 = 150
* 233 + 542 = 775
*
Row 3:
* 366 - 161 = 205
* 241 + 342 = 583
* 214 - 102 = 112
* 311 + 484 = 795
*
Row 4:
* 134 + 101 = 235
* 113 + 222 = 335
* 859 - 742 = 117
* 999 - 444 = 555
In summary, the worksheet presents 16 unique triple-digit addition and subtraction problems that can be solved without regrouping, and both copies of the worksheet contain the same problems with the same solutions.
