To express it another way:
{| align="center" cellpadding="8" style="text-align:center"
{| align="center" cellpadding="8" style="text-align:center"
| <math>\Upsilon (e, f) = 1\!</math>
| <math>\Upsilon (e, f) = 1\!</math>
| <math>\Leftrightarrow</math>
| <math>\Leftrightarrow</math>
| <math>\underline{(e (f))} = \underline{1}.</math>
| <math>\texttt{(} e \texttt{(} f \texttt{))} = 1</math>
|}

In writing this, however, it is important to notice that the 1's appearing on the left and right have different meanings. Filling in the details, we have:
In writing this, however, it is important to notice that the <math>1\!</math> appearing on the left side and the <math>1\!</math> appearing on the right side of the logical equivalence have different meanings. Filling in the details, we have:
