This article tries to present a possible way of proliferating bivalent, trivalent, etc. calculation. Beyond the controversies as to the effects that involve the presence versus the absence of the temporal factor, no significant attempts of adapting a bivalent logic to other pairs of values have been mentioned. Should the transformation of the alethiologic modalities into logic values be possible, five more bivalent calculations may be added to the classic bivalent calculation. All these new calculations are compatible with the traditional one, to the extent that they submit to the conditions of non-contradictoriness and exhaustibility, and the connectors receive, even if partially, the corresponding value interpretations.
