+# operator-no-newline-before
+
+Disallow linebreaks before Sass operators.
+
+```scss
+a { width: 10px
+    + $n; }
+/** ↑
+ * Linebreaks before this */
+```
+
+This rule checks math operators (`+`, `-`, `/`, `*`, `%`) and comparison operators (`>`, `<`, `!=`, `==`, `>=`, `<=`).
+
+Not all symbols that correspond to math operators are actually considered operators by Sass. Some of the exceptions are:
+
+* `+` and `-` as signs before values;
+* `+` and `-` as signs in [space-delimited lists](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#string_operations);
+* `-` as part of [a string](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#string_operations) or [a Sass identifier](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#subtraction), e.g. a variable;
+* `/` as a CSS delimiter in property values like `font: 10px/1.2 Arial;` ([read more](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#division-and-slash)).
+
+For more details refer to [Sass official documentation](http://sass-lang.com/documentation/file.SASS_REFERENCE.html). An online Sass compiler - [Sassmeister](http://www.sassmeister.com/) - could also come in handy.
+
+The following patterns are considered warnings:
+
+```scss
+a { width: 10
++ 1; }
+```
+
+```scss
+a {
+  width: 10
+    + 1;
+}
+```
+
+The following patterns are *not* considered warnings:
+
+```scss
+a {
+  width: 10px
+    -1; // not a math operator, ignored
+}
+```
+
+```scss
+a { width: 10px     -    1; }
+```
+
+```scss
+a {
+  width: 100px +
+    $var * 0.5625; // the newline is not right before the operator
+}
+```
