PROGRAMMING:A + B (multi group data 1)
###Problem description
There are several groups of integer pairs, and the sum of each logarithm is obtained.
###Input format:
The first line is the number of data groups n (1 < = n < = 100)
The next n rows, each with two integers (no more than 10000 absolute values).
###Output format:
The calculation results of each group of data are displayed on a separate line.
###Input example:
```in
three
18 -299
1 1
-5 8
```
###Output example:
```out
-281
two
three
```
