==multiple arithmetic operators==

<source lang="csharp">class MainClass
{
public static void Main()
{

System.Console.WriteLine("3 * 4 / 2 = " + 3 * 4 / 2);
}
}</source>
<pre class=codeResult>3 * 4 / 2 = 6</pre>

==Operator precedence, with () and without ()==

<source lang="csharp">class MainClass
{
public static void Main()
{
int myInt = 2 + 5 * 10;
System.Console.WriteLine("2 + 5 * 10 = " + myInt);

System.Console.WriteLine("(2 + 5) * 10 = " + myInt);
myInt = 2 * 20 / 5;
System.Console.WriteLine("2 * 20 / 5 = " + myInt);
}
}</source>
<pre class=codeResult>2 + 5 * 10 = 52
(2 + 5) * 10 = 70
2 * 20 / 5 = 8</pre>
