<gadget id="calculator">40 * 8</gadget>
<output>320</output>

<gadget id="calculator">25 / 100</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">40 * (1/4)</gadget>
<output>10</output>

<gadget id="calculator">40 + 10</gadget>
<output>50</output>

<gadget id="calculator">320 / 50</gadget>
<output>32/5 = around 6.4</output>

<result>32/5 = around 6.4</result>
