    Let "food" be Universe; ${\displaystyle m}$ = "sweet"; ${\displaystyle x}$ = "sugar"; ${\displaystyle y}$ = "salt".

    All ${\displaystyle x}$ are ${\displaystyle m}$; All ${\displaystyle y}$ are ${\displaystyle m^{\prime }}$.	${\displaystyle \scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}}$	∴	${\displaystyle \scriptstyle {\left\{{\begin{matrix}\ \\\ \end{matrix}}\right.}}$	All ${\displaystyle x}$ are ${\displaystyle y^{\prime }}$. All ${\displaystyle y}$ are ${\displaystyle x^{\prime }}$.

    i.e.	${\displaystyle \scriptstyle {\left\{{\begin{matrix}\ \\\ \end{matrix}}\right.}}$	Sugar is not salt. Salt is not sugar.

    Let "Things" be Universe; ${\displaystyle m}$ = "eggs"; ${\displaystyle x}$ = "hard-boiled"; ${\displaystyle y}$ = "crackable".

    Some ${\displaystyle m}$ are ${\displaystyle x}$; No ${\displaystyle m}$ are ${\displaystyle y^{\prime }}$.	${\displaystyle \scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}}$	∴ Some ${\displaystyle x}$ are ${\displaystyle y}$.

    i.e. Some hard-boiled things can be cracked.
