<gadget id="calculator">3 / 5</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">2 / 5</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">(3/5) - (2/5)</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">(3/5) + (1/5) + (2/5)</gadget>
<output>6/5 = around 1.2</output>

<result>6/5 = around 1.2</result>
