 1. Start
2. Read two numbers and store them in num1 and num2
3. Compute sum = num1 + num2
4. Compute difference = num1 - num2
5. Compute product = num1 * num2
6. If num2 ≠ 0, compute quotient = num1 / num2
7. Display sum, difference, product, and quotient (if applicable)
8. If num2 = 0, display "Division by zero is not allowed"
9. End
