Given two numbers A and B. Perform addition, subtraction, division and multiplication on these two numbers and display result in a new line.

**Input: **First line of the input contains an integer T which denotes the number of test cases. Then T test cases follow. Each test case contains a single line containing two space separated integers A and B.

**Output: **There should be four lines of output for each test case. Description of the 4 lines is shown below:

First Line: Result of addition of the two numbers

Second Line: Result of subtracting the smaller number from the greater number.

Third Line: Result of dividing greater number by the smaller number (Result will be in integer)

Fourth Line: Result of multiplication of the two numbers.

**Constraints:**

1 <= T< = 100

1<=A<=1000

1<=B<=1000
