Peter the reindeer is preparing for the NPCO (North Pole Computing Olympiad) and comes over the following problem:

You are given two integers $a$ and $b$. Output $a+b$, $a-b$, and $a\times b$ on separate lines, respectively.

Peter believes he can output $a+b$ successfully but requires help with the others. Could you help Peter solve his problem?

Input Specification

The first line contains $a$ $(1\le a\le {10}^3)$.

The second line contains $b$ $(1\le b\le {10}^3)$.

Output Specification

Output the value of $a+b$, $a-b$, and $a\times b$ on three separate lines. For clarification, refer to the sample output below.

Sample Input 1

2
3

Sample Output 1

5
-1
6

Explanation

Each line of output represents one of $(a+b,a-b,a\times b)$.

• The first line is $a+b=2+3=5$.
• The second line is $a-b=2-3=-1$.
• The third line is $a\times b=2\times 3=6$.
