Step-1: Start
Step-2: Read the variables a and b
Step-3: Options Desplay
Step-4: Read the input choice
Step-5: If Choice is
- 1 then execute step 6
- 2 then execute step 7
- 3 then execute step 8
- 4 then execute step 9
- Other than above mentioned choice than execute step 10

Step-6: Addition of a and b
Step-7: Substraction of a and b
Step-8: Multiplication of a and b
Step-9: Division of a and b
Step-10: Invalid choice
Step-11: Print the result
Step-12: Stop
