Hi, I have recently encountered an issue in calculating the inverse matrix with non-commutative elements:
```
A, C, D = sympy.symbols('A C D', commutative=False)
X = sympy.Matrix([[A, C], [C, D]])

The algebraic operators `dot`, `cross`, `inner` and `outer` do not handle correctly `Matrix` objects from sympy.
We consider the following
```python
from sympde.topology import VectorFunctionS…

`cancel` raises `PolynomialError` for expressions like `exp(1+O(x))`.
This issue came across in [20936(comment)](https://github.com/sympy/sympy/pull/20936#discussion_r575637283).
Traceback looks l…

- For Commutative infixExpressions ignore the order of operands
- For non-Commutative force specific order as was in the pattern.
- Support both cases of 2 operands and also more than 2 operands

Hi!
When I apply the modifiers `associative commutative ` on a symbol, and if I have a term with this symbol in the hypothesis of a proof, Lambdapi automatically puts it in its normal form. Where I…

In line with the discussion in https://github.com/ramda/ramda/issues/2160, I wonder about the consensus to add `CFoldable` aka Commutative-Foldable, where `reduce` only needs to be defined and obey th…
