PROGRAMMING:Introduction to arithmetic: addition, subtraction, multiplication and division

For the input two integers, the sum difference product quotient is output as required.
###Input format:
Enter two non negative integers a and B no more than 100 in one line, with a space between them, and ensure that B is not 0.
###Output format:
There are four lines in total
```
[a] + [b] = [a+b]
[a] - [b] = [a-b]
[a] * [b] = [a*b]
[a] / [b] = [a/b]
```
Among them, the content with square brackets (such as' [a] ',' [b] ',' [a + b] ') represents the value of the corresponding integer or operation result, which should be replaced by the actual value in the output.
And: if a can be divided by B, then a / B should be output in integer format, otherwise a / B should be output in the format with two decimal places.
**Tip: * * pay attention to the space in the expression.
###Input sample 1:
```in
6 3
```
###Output sample 1:
```out
6 + 3 = 9
6 - 3 = 3
6 * 3 = 18
6 / 3 = 2
```
###Input sample 2:
```
8 6
```
###Output sample 2:
```
8 + 6 = 14
8 - 6 = 2
8 * 6 = 48
8 / 6 = 1.33
```
