Read 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.
   

a = 3
b = 5

Print the following:

8
-2
15

The first line contains the first integer, a
The second line contains the second integer, b

1 <= a <= 10¹⁰
1 <= b <= 10¹⁰

Print the three lines as explained above

3
2

5
1
6

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