Arithmetic Operators

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 second integer, b.

Constraints:
    1 <= a <= 10^10
    1 <= b <= 10^10

Output Format:
    Print the three lines as explained above.
