How to convert a mathematical expression of type AND or OR into a mathematical expression of type OR and?
The basic methods of transforming AND-OR type into OR-OR type are: using duality rules to find the dual type of AND-OR type, and expanding and simplifying the dual type; Finally, the dual formula is transformed to obtain the OR-AND logic formula.

Here, please pay attention to the dual transformation of and or formula, get or and formula, expand to get and or formula, and then get or and formula.

The logical function definition expression is:

Where: A 1, A2, ..., An are input logic variables, and the value is 0 or1;

F is the output logic variable, and its value is 0 or1;

F is called the output logic function of A 1, A2, ..., Ann.

There are two standard forms of logical function: the sum of the smallest term and the product of the largest term.
