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~.
