1. Start
2. Initialize two integer variables:
- `a = 101`
- `b = 2`
3. Define a function `sum(num1, num2)`:
- Calculate the addition: `sum = num1 + num2`
- Return `sum`
4. Define a function `subtract(num1, num2)`:
- Calculate the difference: `sub = num1 - num2`
- Return `sub`
5. Define a function `multiply(num1, num2)`:
- Calculate the product: `mul = num1 * num2`
- Return `mul`
6. Define a function `divide(num1, num2)`:
- Calculate the division: `divi = num1 / num2`
- Return `divi`
7. Call the functions with inputs `a` and `b`:
- Call `sum(a, b)` and store result.
- Call `subtract(a, b)` and store result.
- Call `multiply(a, b)` and store result.
- Call `divide(a, b)` and store result.
8. Print outputs:
- Display "Sum of two numbers value is :" followed by the sum result
- Display "Difference of two numbers value is :" followed by the difference result
- Display "Multiplication of two numbers value is :" followed by the product result
- Display "Division of two numbers value is :" followed by the division result
9. End
