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

<gadget id="calculator">54 * (1/5)</gadget>
<output>54/5 = around 10.8</output>

<gadget id="calculator">100 - 54</gadget>
<output>46</output>

<gadget id="calculator">(54/5) + 4 + 46</gadget>
<output>304/5 = around 60.8</output>

<gadget id="calculator">(304/5) / (1/5)</gadget>
<output>304</output>
