Subtraction practice worksheet for 1- to 3-digit numbers.

Problem Description:

The task involves solving a series of subtraction problems where the numbers range from 1-digit to 3-digit. Each problem requires calculating the difference between two numbers.

Solution Approach:

We will solve each subtraction problem step by step, ensuring proper borrowing when necessary. Let's go through each row and column systematically.

Final Answer:

Here are all the differences calculated:

```
792 - 415 = 377
215 - 3 = 212
546 - 89 = 457
155 - 114 = 41
75 - 50 = 25

6 - 5 = 1
123 - 3 = 120
8 - 5 = 3
10 - 10 = 0
76 - 6 = 70

3 - 1 = 2
205 - 89 = 116
939 - 7 = 932
90 - 23 = 67
2 - 2 = 0

38 - 7 = 31
195 - 116 = 79
9 - 8 = 1
401 - 42 = 359
21 - 6 = 15

121 - 37 = 84
22 - 9 = 13
967 - 670 = 297
507 - 297 = 210
3 - 2 = 1
```

Thus, the final answer is:
\[
\boxed{377, 212, 457, 41, 25, 1, 120, 3, 0, 70, 2, 116, 932, 67, 0, 31, 79, 1, 359, 15, 84, 13, 297, 210, 1}
