# Math in PythonΒΆ

division can be a touch odd. Here are some interesting examples of division:

```
>>> 17 / 3 # classic division returns a float
5.666666666666667
>>>
>>> 17 // 3 # floor division discards the fractional part
5
>>> 17 % 3 # the % operator returns the remainder of the division
2
>>> 5 * 3 + 2 # result * divisor + remainder
17
```

- division operators:
- // floor division; division that rounds down to nearest integer.
- % calculate just the remainder from division.

Also you can calculate powers:

```
>>> 5 ** 2 # 5 squared
25
>>> 2 ** 7 # 2 to the power of 7
128
```

There is a lot more math around, if you are a math-type person, but I’ll finish off here with one more thing, you can do grouping with () as expected when doing math on paper:

```
>>> 50 - 5*6
20
>>> (50 - 5*6) / 4
5.0
```

- So our complete list of operators on numbers:
- addition: +
- subtraction: -
- multiplication: *
- division: /
- // floor division; division that rounds down to nearest integer.
- % calculate just the remainder from division.
- ** powers (squaring numbers)
- () grouping
