The hexagram structure itself already means disbalance between organs. From this point of view disbalance between organs is quite a normal phenomenon. Thus, there are both favourable and unfavourable hexagrams, and there are favourable, and unfavourable disbalances of organs for the season given. In this case the terms above are the notions of definite mathematical operations. This theory can be translated into modern mathematical language but it is mush easier to use those symbols listed in it.
French nomenclature is used.
