<gadget id="calculator">1 / 8</gadget>
<output>1/8 = around 0.125</output>

<gadget id="calculator">1 / 2</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">(1/2) / 8</gadget>
<output>1/16 = around 0.0625</output>

<gadget id="calculator">(1/8) + (1/16)</gadget>
<output>3/16 = around 0.1875</output>

<gadget id="calculator">1 / (3/16)</gadget>
<output>16/3 = around 5.333333</output>

<result>16/3 = around 5.333333</result>
