The development of differential logic is greatly facilitated by having a conceptually efficient calculus in place at the level of [[boolean-valued functions]] and elementary logical propositions.  A calculus that is very efficient from both conceptual and computational standpoints is based on just two types of logical connectives, both of variable <math>k\!</math>-ary scope.  The formulas of this calculus map into a species of graph-theoretical structures called ''painted and rooted cacti'' (PARCs) that lend visual representation to their functional structure and smooth the path to efficient computation.
