""" """
Make calculus as a student Make calculus as a student
==========================
Expression is the classe wich handle all calculus. It can randomly generate or import calculus, simplify them and explain them as a student would do.
>>> from mapytex.calculus import Expression
>>> e = Expression.from_str("2x + 6 - 3x")
>>> print(e)
2x + 6 - 3x
>>> f = e.simplify()
>>> print(f)
- x + 6
>>> for s in f.explain():
... print(s)
2x + 6 - 3x
2x - 3x + 6
(2 - 3) * x + 6
- x + 6
