Description
mmmmm, my bra is on backwards, and the outside is in.
Doesn’t commute.

Demonstration of the commutative property:
it relates to the order of operations.
[a,b] = ab - ba = 0 if the order of the operations does not matter.
For example, [3,2] = 3x2 - 2x3 = 6 - 6 = 0.
When does order matter?
• vector products.
• clothes.
The order you put them on matters.
Not convinced?
Be brave and go out in public with your under garments on the outside.
