Task

The provided code stub reads two integers from STDIN, a and b.

Add code to print three lines where:

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

Example

a = 3

b = 5

Print the following:

8
-2
15

Input Format The first line contains the first integer, a. The second line contains the first integer, b.

Constraints

1 <= a <= 10^10

1 <= b <= 10^10

Output Format

Print the three lines as explained above,

Sample Input 0

3
2

Sample Output 0

5
1
6

Explanation 0

3 + 2 => 5
3 - 2 => 1
3 * 2 => 6

Code

Starter

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

Solution

Straightforward

If we translate 1:1 the instructions given in the Problem section, we can quickly write each operation as a simple as-is statement in Python:

if __name__ == '__main__':
    a = int(input())
    b = int(input())
    print(a + b)
    print(a - b)
    print(a * b)

One-liner

We can avoid repeating writing print manually 3 times, for each statement, using instead a single print with each statement printed a new line using the separation \n:

if __name__ == '__main__':
    a = int(input())
    b = int(input())
    print(a + b, a - b, a * b, sep="\n")
