* For a negative sign or subtraction operator, use a minus sign ({{xt|−}}, Unicode character U+2212 MINUS SIGN). Input by clicking on it in the insert box beneath the edit window or by typing <code>&minus;</code>.

* For a multiplication sign between numbers, use {{xt|×}} (Unicode character U+00D7 MULTIPLICATION SIGN), which is input by clicking on it in the edit toolbox under the edit window or by typing <code>&times;</code>. The letter {{xt|x}} should not be used to indicate multiplication, but it is used (unspaced) as the substitute for "by" in terms such as {{xt|[[4x4]]}}.

* [[Exponentiation]] is indicated by a superscript, {{xt|~~{{var|~~a}}~~{{var|~~n}}}} (typed as <code><nowiki>''a''''n''</nowiki></code> ~~or <code><nowiki>{{var|a}}{{var|n}}</nowiki></code>)~~. [[Exponential notation]] can be spaced or unspaced, depending on circumstances.

* [[Wikipedia:Exponentiation|Exponentiation]] is indicated by a superscript, {{xt|''a''''n''}} (typed as <code><nowiki>''a''''n''</nowiki></code>. [[Wikipedia:Exponential notation|Exponential notation]] can be spaced or unspaced, depending on circumstances.

* Do not use programming language notation outside computer program listings. In most programming languages, subtraction, multiplication, and exponentiation are respectively represented by the [[hyphen-minus]] <code>-</code>, the [[asterisk]] <code>*</code>, and either the [[caret]] <code>^</code> or the double asterisk <code>**</code>, and [[scientific notation]] is replaced by [[E notation]].

* Symbols for [[Wikipedia:Binary operator|binary operators]] and [[Wikipedia:Binary relation|relations]] are spaced on both sides:

** plus, minus, and plus-or-minus (as binary operators): {{xt|+}}, {{xt|−}}, {{xt|±}} (as in {{xt|5 − 3}});

** multiplication and division: {{xt|×}}, {{xt|÷}};

** equals, does not equal, equals approximately: {{xt|{{=}}}}, {{xt|≠}}, {{xt|≈}};

** equals, does not equal, equals approximately: {{xt|<nowiki>=</nowiki>}}, {{xt|≠}}, {{xt|≈}};

** is less than, is less than or equal to, is greater than, is greater than or equal to: {{xt|<}}, {{xt|≤}}, {{xt|>}}, {{xt|≥}}.

* Symbols for [[unary ~~operator~~]]s are closed-up to their operand:

* Symbols for [[Wikipedia:Unary operator|unary operators]] are closed-up to their operand:

** positive, negative, and positive-or-negative signs: {{xt|+}}, {{xt|−}}, {{xt|±}} (as in {{xt|−3}});

** other unary operators, such as the exclamation mark as a [[factorial]] sign (as in {{xt|5!}}).

** other unary operators, such as the exclamation mark as a [[Wikipedia:Factorial|factorial]] sign (as in {{xt|5!}}).

* Variables are italicized, but digits and punctuation are not; only ~~{{var|~~x}} and ~~{{var|~~y}} are italicized in {{xt|2(5''x'' + ''y'')2}}. The [[semantic HTML]] element {{tag~~|var}}, or its template wrapper {{tlx~~|var}} can be used to distinguish variables from other uses of italics, as illustrated in the code example above.
