Problem:
Simple Calculator

Write a program which reads two integers a, b and an operator op, and then prints the value of a op b.

The operator op is '+', '-', '*' or '/' (sum, difference, product or quotient). The division should truncate any fractional part.

Input

The input consists of multiple datasets. Each dataset is given in the following format.

a op b

The input ends with a dataset where op = '?'. Your program should not process for this dataset.

Output

For each dataset, print the value in a line.

Constraints

0 ≤ a, b ≤ 20000

No divisions by zero are given.

Sample Input 1

1 + 2
56 - 18
13 * 2
100 / 10
27 + 81
0 ? 0

Sample Output 1

3
38
26
10
108
