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

<gadget id="calculator">3 / 8</gadget>
<output>3/8 = around 0.375</output>

<gadget id="calculator">1 - (1/8) - (3/8)</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">(1/2) - (1/8)</gadget>
<output>3/8 = around 0.375</output>

<result>3/8 = around 0.375</result>
