Hi, all.  I am working on a document where I would like to use the \[
\] (displaymath) form.  The problem is that I am using multiline
formulas (unnumbered) with fractions.  I have discovered (through a
bit of experimentation) that anytime I use an eqnarray* with a tab, it
"shrinks" my fractions and makes them unreadble after the tab.

For example, the latex code
\begin{eqnarray*}
\chi^2  = & \frac{(65 - 50)^2}{50} + \frac{(35 - 50)^2}{50} \\
        = & \frac{15^2}{50} + \frac{15^2}{50} \\
        = & \frac{255}{50} + \frac{255}{50} \\
        = & 4.5 + 4.5 \\
        = & 9
\end{eqnarray*}
makes small fractions, and I want full size fractions, like
\[
\chi^2  =  \frac{(65 - 50)^2}{50} + \frac{(35 - 50)^2}{50} 
        =  \frac{15^2}{50} + \frac{15^2}{50} 
        =  \frac{255}{50} + \frac{255}{50} 
        =  4.5 + 4.5 
        =  9
\]

Does anyone know why latex shrinks fractions in \eqnarray after an &?

thanks for the help?
