👉 In mathematics, a commutation is a mathematical operation that swaps two operands. It is one of the basic operations in abstract algebra and functional analysis. The commutator of two elements A and B is defined as AB - BA.
For example:
- Commute between "a" and "b": (a
b) - (b
a)
- Commute between "x" and "y": x
y - y
x
The commutation operation can be used to simplify certain mathematical
