An [[ideal]] in a [[commutative unital ring]] is termed a &amp;#039;&amp;#039;&amp;#039;proper ideal&amp;#039;&amp;#039;&amp;#039; if it satisfies the following equivalent conditions:&lt;br /&gt;
&lt;br /&gt;
* The element &amp;lt;math&amp;gt;1&amp;lt;/math&amp;gt; of the ring, does &amp;#039;&amp;#039;not&amp;#039;&amp;#039; lie inside the ideal&lt;br /&gt;
* The ideal is not equal to the whole ring&lt;br /&gt;
&lt;br /&gt;
===Definition with symbols===&lt;br /&gt;
&lt;br /&gt;
An [[ideal]] &amp;lt;math&amp;gt;I&amp;lt;/math&amp;gt; in a [[commutative unital ring]] &amp;lt;math&amp;gt;R&amp;lt;/math&amp;gt; is termed a &amp;#039;&amp;#039;&amp;#039;proper ideal&amp;#039;&amp;#039;&amp;#039; if it satisfies the following equivalent conditions:&lt;br /&gt;
&lt;br /&gt;
* &amp;lt;math&amp;gt;1 \notin I&amp;lt;/math&amp;gt;&lt;br /&gt;
* &amp;lt;math&amp;gt;I \ne R&amp;lt;/math&amp;gt;&lt;/div&gt;</summary>
