In one of the beautiful cities of Afghanistan two sisters are going to program a simple game to help them solve their mathematics homework. Their homework asks them to calculate the sum and multiplication of two numbers. Your task is to help them to build a simple program for their homework.
First line contains the number of test cases (T): 1 ≤ T ≤ 1000
Second line represents the number of problems.1 ≤ N ≤ 50
Next N lines contains two integer numbers. 0 ≤ number ≤ 20000
For every input expecting two integer numbers, first one represents the addition of two given numbers and second represents the multiplication separated by space.
1 2 20 30 40 60
50 600 100 2400
