You are working as the software tester for a large school and need to test the exam calculator for students. Your school does not want students to use a physical calculator. The software development team has released a calculator application. You need to ensure that everything is working as expected.

Address the following:

• Download the calculator executable file and source code file.
• Write the functional test cases for the Calculator application. Here is the sample test case document.
• You need to create the Excel file with the following columns:

1. Test Case ID
2. Test Case Name
3. Test Case Scenario
4. Detailed Test Steps
5. Test Data
6. Expected Results
7. Actual Results After Test Case Execution

• Create at least 20 test cases in a single Excel file.
• Execute each of the test cases, and update the actual results in the After Test Case Execution column.
• Provide an explanation as to whether the school should release this calculator to students.
