-<p>Sometimes you want the display math typographical treatment to happen in

+<p>TeX’s rules for typesetting a formula depend on the context. For
+example, inside a displayed equation, the input <code>\sum_{0\leq
+i<n}k^m=\frac{n^{m+1}}{m+1}+\mbox{lower order terms}</code> will give
+output with the summation index centered below the summation symbol.
+But if that input is inline then the summation index is off to the right
+rather than below, so it won’t push the lines apart. Similarly, in a
+displayed context, the symbols in the numerator and denominator will be
+larger than for an inline context, and in display math subscripts and
+superscripts are further apart then they are in inline math.
+</p>
+<p>TeX uses four math styles.
+</p>
+<ul>
+<li> <span id="index-display-style"></span>
+Display style is for a formula displayed on a line by itself, such as
+with <code>\begin{equation} ... \end{equation}</code>.
+
+</li><li> <span id="index-text-style"></span>
+Text style is for an inline formula, as with ‘<samp>so we have $ ... $</samp>’.
+
+</li><li> <span id="index-script-style"></span>
+Script style is for parts of a formula in a subscript or superscript.
+
+</li><li> <span id="index-scriptscript-style"></span>
+Scriptscript style is for parts of a formula at a second level (or more)
+of subscripting or superscripting.
+
+</li></ul>

+<span id="index-_005cdisplaystyle"></span>
+<span id="index-_005ctextstyle"></span>
+<span id="index-_005cscriptstyle"></span>
+<span id="index-_005cscriptscriptstyle"></span>
+<p>TeX determines a default math style but you can override it with a
+declaration of <code>\displaystyle</code>, or <code>\textstyle</code>, or
+<code>\scriptstyle</code>, or <code>\scriptscriptstyle</code>.
+</p>
+<p>In this example, the ‘<samp>Arithmetic</samp>’ line’s fraction will look
+scrunched.
+</p>
+<div class="example">
+<pre class="example">\begin{tabular}{r|cc}
+ \textsc{Name} &\textsc{Series} &\textsc{Sum} \\ \hline
+ Arithmetic &$a+(a+b)+(a+2b)+\cdots+(a+(n-1)b)$
+ &$na+(n-1)n\cdot\frac{b}{2}$ \\
+ Geometric &$a+ab+ab^2+\cdots+ab^{n-1}$
+ &$\displaystyle a\cdot\frac{1-b^n}{1-b}$ \\
+\end{tabular}
+</pre></div>
+
+<p>But because of the <code>\displaystyle</code> declaration,
+the ‘<samp>Geometric</samp>’ line’s fraction will be easy to read, with
+characters the same size as in the rest of the line.
+</p>
+<p>Another example is that, compared to the same input without the
+declaration, the result of
+</p>
+<div class="example">
+<pre class="example">we get
+$\pi=2\cdot{\displaystyle\int_{x=0}^1 \sqrt{1-x^2}\,dx}$
+</pre></div>
+
+<p>will have an integral sign that is much taller. Note that here the
+<code>\displaystyle</code> applies to only part of the formula, and it is
+delimited by being inside curly braces, as ‘<samp>{\displaystyle ...}</samp>’.
+</p>
+<p>The last example is a continued fraction.
+</p>
+<div class="example">
+<pre class="example">\begin{equation}
+a_0+\frac{1}{
+ \displaystyle a_1+\frac{\mathstrut 1}{
+ \displaystyle a_2+\frac{\mathstrut 1}{
+ \displaystyle a_3}}}
+\end{equation}
+</pre></div>
+
+<p>Without the <code>\displaystyle</code> declarations, the denominators would be
+set in script style and scriptscript style. (The <code>\mathstrut</code>
+improves the height of the denominators; see <a href="#g_t_005cmathstrut">\mathstrut</a>.)

-16.7 Math miscellany
+16.7 Math styles
+================
+
+TeX's rules for typesetting a formula depend on the context. For
+example, inside a displayed equation, the input '\sum_{0\leq
+i<n}k^m=\frac{n^{m+1}}{m+1}+\mbox{lower order terms}' will give output
+with the summation index centered below the summation symbol. But if
+that input is inline then the summation index is off to the right rather
+than below, so it won't push the lines apart. Similarly, in a displayed
+context, the symbols in the numerator and denominator will be larger
+than for an inline context, and in display math subscripts and
+superscripts are further apart then they are in inline math.
+
+ TeX uses four math styles.
+
+ * Display style is for a formula displayed on a line by itself, such
+ as with '\begin{equation} ... \end{equation}'.
+
+ * Text style is for an inline formula, as with 'so we have $ ... $'.
+
+ * Script style is for parts of a formula in a subscript or
+ superscript.
+
+ * Scriptscript style is for parts of a formula at a second level (or
+ more) of subscripting or superscripting.
+
+ TeX determines a default math style but you can override it with a
+declaration of '\displaystyle', or '\textstyle', or '\scriptstyle', or
+'\scriptscriptstyle'.
+
+ In this example, the 'Arithmetic' line's fraction will look
+scrunched.
+
+ \begin{tabular}{r|cc}
+ \textsc{Name} &\textsc{Series} &\textsc{Sum} \\ \hline
+ Arithmetic &$a+(a+b)+(a+2b)+\cdots+(a+(n-1)b)$
+ &$na+(n-1)n\cdot\frac{b}{2}$ \\
+ Geometric &$a+ab+ab^2+\cdots+ab^{n-1}$
+ &$\displaystyle a\cdot\frac{1-b^n}{1-b}$ \\
+ \end{tabular}
+
+But because of the '\displaystyle' declaration, the 'Geometric' line's
+fraction will be easy to read, with characters the same size as in the
+rest of the line.
+
+ Another example is that, compared to the same input without the
+declaration, the result of
+
+ we get
+ $\pi=2\cdot{\displaystyle\int_{x=0}^1 \sqrt{1-x^2}\,dx}$
+
+will have an integral sign that is much taller. Note that here the
+'\displaystyle' applies to only part of the formula, and it is delimited
+by being inside curly braces, as '{\displaystyle ...}'.
+
+ The last example is a continued fraction.
+
+ \begin{equation}
+ a_0+\frac{1}{
+ \displaystyle a_1+\frac{\mathstrut 1}{
+ \displaystyle a_2+\frac{\mathstrut 1}{
+ \displaystyle a_3}}}
+ \end{equation}
+
+Without the '\displaystyle' declarations, the denominators would be set
+in script style and scriptscript style. (The '\mathstrut' improves the
+height of the denominators; *note \mathstrut::.)

+output with the summation index centered below the summation symbol.
+But if that input is inline then the summation index is off to the right
+rather than below, so it won't push the lines apart. Similarly, in a
+displayed context, the symbols in the numerator and denominator will be
+larger than for an inline context, and in display math subscripts and
