Economics is considered as the commodity-financial exchange process. Two parallel networks are processed: commodity-production and financial. Economics is the set of the production-consumption elements and the channels or connections among them. Market is the transference process through the channels. The financial network processing is the reflection of the commodity-production network processing. The couples of the production and financial equations are based on the algebra of the multi-dimensional matrices. Different levels of the economics (micro-, macro-, global-) have the similar structures of difference dynamic equations.
