<gadget id="calculator">1 / 4</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">(1/4) * 22</gadget>
<output>11/2 = around 5.5</output>

<gadget id="calculator">(11/2) - 1</gadget>
<output>9/2 = around 4.5</output>

<gadget id="calculator">1 / 5</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">(1/5) + (1/4)</gadget>
<output>9/20 = around 0.45</output>

<gadget id="calculator">(9/2) / (9/20)</gadget>
