<gadget id="calculator">2 / 3</gadget>
<output>2/3 = around 0.666667</output>

<gadget id="calculator">1 + (2/3) + 1</gadget>
<output>8/3 = around 2.666667</output>

<gadget id="calculator">400 / (8/3)</gadget>
<output>150</output>

<gadget id="calculator">150 * (2/3)</gadget>
<output>100</output>

<gadget id="calculator">150 + 100</gadget>
<output>250</output>

<result>250</result>
