PROGRAMMING:Four arithmetic operations of integers
This problem requires the preparation of procedures to calculate the sum, difference, product, quotient of two positive integers and output. Ensure that the input and output are all in the integer range.
###Input format:
The input gives two positive integers a and B in one line.
###Output format:
Output sum, difference, product and quotient in the order of "a operator, B = result" in 4 lines.
###Input example:
```in
3 2
```
###Output example:
```out
3 + 2 = 5
3 - 2 = 1
3 * 2 = 6
3 / 2 = 1
```
