Problem 3:

Read two integers from STDIN and print three lines where:

The first line contains the sum of the two numbers.
The second line contains the difference of the two numbers (first - second).
The third line contains the product of the two numbers.

if __name__ == '__main__':
    a = int(input())
    b = int(input())

    print(a+b)
    print(a-b)
    print(a*b)
