Unary refers to operators that affect one placeholder. Binary refers to operators that connect two placeholders. The lower area of the Elements pane displays the individual operators.

<paragraph role="paragraph" id="par_id3150464" xml-lang="en-US">You can also insert user-defined unary operators by typing <emph>uoper</emph> in the <emph>Commands</emph> window, followed by the syntax for the character. This function is useful for incorporating special characters into a formula. For example, the command <emph>uoper %theta x</emph> produces a small Greek letter theta (a component of the <emph>$[officename] Math</emph> character set). You can also insert characters not in the $[officename] character set by choosing <emph>Tools - Symbols - Edit</emph>.</paragraph>
<paragraph role="paragraph" id="par_id3154725" xml-lang="en-US"> You can also insert user-defined binary commands by typing <emph>boper</emph> into the <emph>Commands</emph> window. For example, the command <emph>y boper %theta x</emph> produces the small Greek letter theta preceded by a <emph>y</emph> and followed by an <emph>x</emph>. You can also insert characters not in the $[officename] character set by choosing <emph>Tools - Symbols - Edit</emph>.</paragraph>
<paragraph role="paragraph" id="par_id3150906" xml-lang="en-US">By typing <emph><?>oplus<?></emph> in the <emph>Commands</emph> window, you insert a <emph>circled plus operator</emph> in your document.</paragraph>

<paragraph role="tip" id="par_id3155383" xml-lang="en-US">If you want to use a colon ':' as division sign, choose <emph>Tools - Symbols</emph> or click the <emph>Symbols</emph> icon on the Tools bar. Click the <emph>Edit</emph> button in the dialog that appears, then select the <emph>Special</emph> symbol set. Enter a meaningful name next to <emph>Symbol</emph>, for example, "divide" and then click the colon in the set of symbols. Click <emph>Add</emph> and then <emph>OK</emph>. Click <emph>OK</emph> to close the <emph>Symbols</emph> dialog,too. Now you can use the new symbol, in this case the colon, by entering its name in the Commands window, for example, <emph>a %divide b = c</emph>.</paragraph>
<paragraph role="warning" id="par_id3147398" xml-lang="en-US">When entering information manually in the Commands window, please note that a number of operators require spaces between the elements for the correct structure. This is especially true if you are using values instead of placeholders in your operators, for example, to construct a division 4 div 3 or a div b.</paragraph>
