-<para>When you click <guibutton>Exp</guibutton>, the calculator displays <literal>. +</literal> to represent <replaceable>base</replaceable> to the power of the next number that you enter. To change the sign of the number, use the <guibutton>+/-</guibutton> button before the <guibutton>Exp</guibutton> button or in the last action of the operation. The following example shows the value that is displayed when you use the decimal numeric base: </para>

+<para>To change the sign of the number, use the <guibutton>+/-</guibutton> button before the <guibutton>Exp</guibutton> button.
+How you change the sign of the exponent (the power to which the number is raised) depends on whether you are in
+arithmetic precedence mode or not. In arithmetic precedence mode, use <guibutton>-</guibutton> after the
+<guibutton>Exp</guibutton> button, otherwise use the <guibutton>+/-</guibutton> button
+after entering the exponent.</para>
