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. For each test case there will be single line which contains two space seperated 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.
1 <= T <= 100
1 <= A <= 1000
1 <= B <= 1000
