Most browsers apply font-style to "italic" when rendering <var>. This can be overridden in CSS, like this:
var { font-style: normal; }
Examples
Basic example
Here's a simple example, using <var> to denote variable names in a mathematical equation.
<p>A simple equation: <var>x</var> = <var>y</var> + 2 </p>

Overriding the default style
Using CSS, you can override the default style for the <var> element. In this example, variable names are rendered using bold Courier if it's available, otherwise it falls back to the default monospace font.
CSS
var { font: bold 15px "Courier", "Courier New", monospace; }
HTML
<p>The variables <var>minSpeed</var> and <var>maxSpeed</var> control the minimum and maximum speed of the apparatus in revolutions per minute (RPM).</p>
