Subtraction without regrouping worksheet for kids with turtle illustration.

Problem Description:

The image shows a subtraction worksheet titled "Subtraction Without Regrouping." The task is to solve each subtraction problem listed in the grid. Since the problems are labeled as "Without Regrouping," it means that no borrowing (regrouping) is required during the subtraction process.

Solution Approach:

1. Understand the Task: Each subtraction problem involves subtracting two numbers where the digits in the minuend (top number) are greater than or equal to the corresponding digits in the subtrahend (bottom number). This ensures no regrouping is needed.
2. Solve Each Problem: Perform the subtraction for each pair of numbers step by step.
3. Verify the Results: Ensure that no borrowing is required and that the calculations are correct.

Final Answer:

The solutions to the subtraction problems are as follows:

| 89 - 42 | 66 - 35 | 78 - 25 | 56 - 24 | 65 - 31 | 93 - 52 | 88 - 65 | 38 - 13 |
|----------|----------|----------|----------|----------|----------|----------|----------|
| 47 | 31 | 53 | 32 | 34 | 41 | 23 | 25 |

| 45 - 34 | 91 - 20 | 83 - 42 | 77 - 14 | 76 - 34 | 49 - 22 | 38 - 21 | 85 - 24 | 56 - 31 | 88 - 14 |
|----------|----------|----------|----------|----------|----------|----------|----------|----------|----------|
| 11 | 71 | 41 | 63 | 42 | 27 | 17 | 61 | 25 | 74 |

Thus, the final answer is:

\[
\boxed{47, 31, 53, 32, 34, 41, 23, 25, 11, 71, 41, 63, 42, 27, 17, 61, 25, 74}
