If the list of arguments is empty, as expressed in the form <math>\texttt{Mno}(),</math> then it cannot be true that exactly one of the arguments is false, so <math>\texttt{Mno}() = \texttt{False}.</math>

If the list of arguments is empty, as expressed in the form <math>\texttt{Mno}(),</math> then it cannot be true that exactly one of the arguments is false, so <math>\texttt{Mno}() = \texttt{False}.</math>

If p is the only argument, then Mno(p) says that p is false, so Mno(p) = Not(p).  

If <math>\texttt{p}</math> is the only argument, then <math>\texttt{Mno(p)}</math> says that <math>\texttt{p}</math> is false, so <math>\texttt{Mno(p)} = \texttt{Not(p)}.</math>

If p and q are the only two arguments, then Mno(p, q) says that exactly one of p, q is false, so Mno(p, q) says the same thing as p ≠ q.

If <math>\texttt{p}</math> and <math>\texttt{q}</math> are the only two arguments, then <math>\texttt{Mno(p, q)}</math> says that exactly one of <math>\texttt{p, q}</math> is false, so <math>\texttt{Mno(p, q)}</math> says the same thing as <math>\texttt{p} \neq \texttt{q}.</math>

The venn diagram for Mno(p, q, r) is shown in Figure 1.

The venn diagram for <math>\texttt{Mno(p, q, r)}</math> is shown in Figure&nbsp;1.
