Solving Your Problem: Troubleshooting Mistakes in Code

In summary, the slides discuss the convention of quantifier scope, which determines how far a quantifier extends to the right in a logical statement. The convention used in the slides is that the scope is maximal, while other textbooks may view the scope as being as small as possible. This can lead to differences in how logical statements are interpreted.

The slides use the convention that the scope of a quantifier is maximal, i.e., it extends as far to the right as possible. In particular, $\forall y\,\text{Animal}(y)\Rightarrow \text{Loves}(x, y)$ means $\forall y\,(\text{Animal}(y)\Rightarrow \text{Loves}(x, y))$ and not $(\forall y\,\text{Animal}(y))\Rightarrow \text{Loves}(x, y)$, as you wrote in the first photo. This convention is not universal, however. Quite a few textbooks view the scope of a quantifier as being as small as possible.
