## Preparation of computer for statistical work

We'll assume that you're using a [\*nix](https://en.wikipedia.org/wiki/Unix-like) operating system, and have [Python](https://www.python.org/) installed.

Create and activate [virtualenv](https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/), and get [fxy](https://pypi.org/project/fxy/) package:

`$ python3 -m venv .venv && . .venv/bin/activate`

`$ pip install fxy`

Type `fx -s` or `isympy` command to get started:

`$ fx -s`

`In [1]: █`

*Note:*

* *`fx` starts IPython environment with* [*mpmath*](https://mpmath.org/) *pre-imported,*
* *parameter `-s` additionally imports* [*sympy*](https://www.sympy.org/) *with* [*isympy*](https://github.com/sympy/sympy/blob/master/isympy.py) *importer.)*
