```

## Examples

### Simplify expressions and explain steps

``` python
>>> from mapytex import Expression
>>> ajout_fractions = Expression("2 / 5 + 2 / 3")
>>> resultat = ajout_fractions.simplify()
>>> print(resultat)
16 / 15 
>>> for s in resultat.explain():
...      print(s)
...
2 / 5  + 2 / 3 
2 \times 3 / 5 \times 3  + 2 \times 5 / 3 \times 5 
6 / 15  + 10 / 15 
6 + 10 / 15 
16 / 15 
```

### Random expression generator

``` python
>>> from mapytex import Expression
>>> ajout_fraction = Expression.random("{a} + {b} / {c}")
>>> print(ajout_fraction)
2 + 3 / 5 
```

### Render in latex

``` python
>>> from mapytex import Expression
>>> Expression.set_render("tex")
>>> ajout_fractions = Expression("2 / 5 + 2 / 3")
>>> for i in ajout_fractions.simpliy().explain():
...      print(i)
...
\frac{ 2 }{ 5 } + \frac{ 2 }{ 3 }
\frac{ 2 \times 3 }{ 5 \times 3 } + \frac{ 2 \times 5 }{ 3 \times 5 }
\frac{ 6 }{ 15 } + \frac{ 10 }{ 15 }
\frac{ 6 + 10 }{ 15 }
\frac{ 16 }{ 15 }
```
