What does it mean that the assignment of small terms is the same as coding in discrete mathematics? What do you mean by the opposite of major events? What does it mean to learn from God and point out the maze? Take two propositional variables as examples. The truth value 1 corresponds to p, q, and the truth value 0 corresponds to non-p and non-q, so the true assignment of an item is the coding arrangement of two propositional variables in the item. For example, the true assignment of p∧q is 1 1, and the true assignment of p∧ (non-q) is 10. The false assignment of an event is the coding arrangement of two propositional variables in the event. For example, the false assignment of p∨q is to change 1 1 into 00 in turn, and the false assignment of p∨ (non-q) is 0 1.
