I am very confused with logic, and the difference between, disjunctions and conjunctions, and where you would put perenthesis, and things like that. Does any one know a easy way to learn it, or can walk me through it.
PLEASE HELP
There are couple of ways to look at this. The difference between conjunction and disjunction is similar to the difference between multiplication and addition. Both * and + are functions of two arguments, but they, obviously, in general return different results for the same arguments. While * and + can be considered as functions of natural numbers, conjunction /\ and disjunction \/ are functions that take and return 0 or 1. In fact, multiplication returns the same result as conjunction on {0, 1}.how do you tell the difference between a disjunction, conjustion, negation, and a biconditional?
Also, you understand the difference between "and" (conjunction) and "or" (disjunction) in the natural language, don't you?
Concerning parentheses, there is an order of operations for functions on {0, 1}, just as there is an order for functions on integers. The usual order is: negation, conjunction, disjunction, implication, biconditional.
