Increasing quantity has no lower (or upper) bound (and gives a representation of negative numbers) vs. increasing quantity has lower bound.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`All left examples have a clear "zero" value, but it may be unclear which side is meant to be positive and which side is meant to be negative (See BP893^left for quantities without clear notion of increase/decrease.)`
	CROSSREFS	`See BP353^left for looping quantities; these do not clearly represent positive and negative numbers, but they can likewise unboundedly decrease and increase.` `See BP870 for a version about upper bounds.` `Adjacent-numbered pages: BP347 BP348 BP349 BP350 BP351 * BP353 BP354 BP355 BP356 BP357`

Two independent quantities changing simultaneously vs. determined by just one changing quantity.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`Examples sorted right may feature multiple quantities, but one changing quantity determines all changing quantities.` `The distinction between the two sides is fuzzy. For example the left-sorted example EX4364 could be viewed as determined by just the one changing quantity of width and the fact that the height is given by two times the width minus one. On the other hand the right-sorted example EX4370 could be viewed as determined by the two changing quantities number of black squares and number of white squares, ignoring the fact that the total number of squares is always six.`

Increasing quantity has upper bound (will get "stopped" by something) vs. not so.

(edit; present; nest [left/right]; search; history)

	CROSSREFS	`See BP352 for a version about lower bounds.` `Related to BP380.` `Adjacent-numbered pages: BP865 BP866 BP867 BP868 BP869 * BP871 BP872 BP873 BP874 BP875`
