| 33 | ### Explanation: |  |  |
| 34 |  |  |  |
| 35 | In this scenario, there were 35 students in third grade at the start of the year. During the year, 20 students left and 15 new students came to school. The task is to determine how many students were in third grade at the end of the year. |  |  |
| 36 |  |  |  |
| 37 | ### Analysis: |  |  |
| 38 |  |  |  |
| 39 | To find out how many students were in third grade at the end of the year, follow these steps: |  |  |
| 40 |  |  |  |
| 41 | 1. Subtract the number of students who left from the total number of students at the start of the year: |  |  |
| 42 | - Total students at the start of the year = 35 |  |  |
| 43 | - Number of students who left = 20 |  |  |
| 44 | - Number of students remaining = 35 - 20 = 15 |  |  |
| 45 |  |  |  |
| 46 | 2. Add the number of new students who joined to the number of students remaining: |  |  |
| 47 | - Number of students remaining = 15 |  |  |
| 48 | - Number of new students who joined = 15 |  |  |
| 49 | - Total number of students at the end of the year = 15 + 15 = 30 |  |  |
| 50 |  |  |  |
| 51 | ### Plan: |  |  |
| 52 |  |  |  |
| 53 | To solve this using SWI-Prolog, we can structure our approach as follows: |  |  |
| 54 |  |  |  |
| 55 | 1. Define a rule "calculate_students" that takes variables for the initial number of students, the number of students who left, and the number of new students who joined. |  |  |
| 56 | 2. Assign constants to the initial number of students, the number of students who left, and the number of new students who joined. |  |  |
| 57 | 3. Use SWI-Prolog's arithmetic capabilities to perform the subtraction and addition operations. |  |  |
| 58 | 4. Test the rule by querying with the specific values provided in the problem. |  |  |
| 59 |  |  |  |
| 60 | This approach leverages Prolog's ability |  |  |
