There are two numbers for the pupils to operate, Mr NEtiger wants to know the answers of plus, minus, multiply, divide,so he can check the answers which the pupils hand in.

The input contain two numbers, you should output the answers in the order of plus, minus, multiply, divide. You may assume that they are dividable and no remainder.

Is it easy? But you should know the numbers may as long as 50 digits.

Sample Input

10 2
15 3

Sample Output

12
8
20

最近真是愈发懒了...

大数的题目，如果真正C/C++写的话还是挺麻烦的...

于是，无耻地用Java水吧，阿弥陀佛...
