How is the order of execution of logical operations in complex expressions determined?

The order should be determined by seniority. From small to large, from beginning to ascending. It is also important whether there are parentheses. In this case, you must first do what is in the brackets, and then, as mentioned above, from the smallest to the largest. If we take in descending order from larger to smaller, then the operations should be arranged as follows: negation, conjunction and the last one is disjunction.
