Understanding the meaning of the disjunctive paradigm and the combined paradigm

Beginners of discrete mathematics will certainly be confused about the meaning of disjunctive paradigm and combined paradigm. First of all, the use of its environment to analyze, the analysis paradigm has a little to think of the circuit or the door, the combined paradigm has a bit like the circuit and the door. And their truth-table is the exact same. We will wonder, how not to call "or take the Paradigm", "and take the Paradigm", this is not more clear and intuitive?

Of course it is so called must have its reason in. Otherwise, discrete mathematics is not like discrete mathematics, but rather like a discrete mathematical circuit.

Discrete mathematics, as a core guiding discipline of many disciplines. It has a strong generalization effect and a practical effect. Many of the problems that you have struggled to understand, using discrete mathematics, you will find something simple. Here the "disjunction" and "take" also have the meaning in, it put "or" and "with" a concept of Ascension, "disjunction", in fact, let its nature, we can interpret it as, "analysis and take", of course, "together" we understand it as "together and take". If you are familiar with our ancient prose students, will definitely understand the meaning of the moment.

Of course, here we translate it into plain English. is, through analysis, to its choice, to choose one of them (disjunctive paradigm). And put all things together to consider, thus getting one of their whole results. (combined paradigm) of course, for a very strict person, must be, all right to stop, then who is that person? He is: "Discrete math!" ”
