Abdullah has a calculator of NASIO brand. [Why NASIO not CASIO is one of the top 10 questions science can not answer]

For the last few days his calculator is giving some weird answers while doing any mathematical operations. Some examples are,

1-1=15

2+2=65

3-3=11

4+4=113

5+7=163

12-4=97

23*11=36196

5/2=19.115385

Given the operation find what Abdullah's calculator will show.

NOTE: For a division operation abdullah's calculator rounds up his result 6 digits after decimal point, and for others he just prints a integer what his system gives.

Input

First line contains an integer 0t<10000, number of testcases.

Next t lines contains the operations in any of these formats 

a+b

a-b

a*b

a/b

where a and b are non-negative integers less than 10⁶ .

See sample testcase for better clarifications.

Output

For each testcase on seperate line print what Abdullah's calculator with show.

Example

Input:
4

1+2

2*3

3/4

4-5

Output:

54

875
