BP1157 The order in which the objects in the top half are combined to make the object in the lower half matters vs. not so.
(edit; present; nest [left/right]; search; history)
COMMENTS

Operations depicted in right-sorted examples are called "commutative".


"Order matters" here means that if the objects in the top half were to switch places, the output would look different.
