<gadget id="calculator">25 * 18</gadget>
<output>450</output>

<gadget id="calculator">20 / 100</gadget>
<output>1/5 = around 0.2</output>

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

<gadget id="calculator">25 * (6/5)</gadget>
<output>30</output>

<gadget id="calculator">450 / 30</gadget>
<output>15</output>

<result>15</result>
