D) The best score in Greek is always higher than the best score in French Switching the order of universal quantifiers does not change the meaning: (Ax)(Ay)P(x,y) is logically equivalent to (Ay)(Ax)P(x,y). We will present † The syntax, or the formal language of first-order logic, that is symbols, formulas, sub-formulas, phd dissertation assistance non formation trees, substitution, etc. In the first step we will convert all the given statements into its first order logic. First Order Logic has this ability, which makes it much more advanced and useful even though it is based on propositional logic theory. An analogical representation, on the other hand, has physical structure that corresponds directly to the structure of the thing represented.
