Explanation:

• The MyMath class provides simple mathematical operations (addition and subtraction).
• The Calculator class takes user input, calls methods from MyMath, and displays the results.
Execution:
• The program prompts the user to enter two numbers, performs addition and subtraction using methods from
MyMath, and displays the results.
• Compile the code:
