<output>5</output>

<gadget id="calculator">25 + 5</gadget>
<output>30</output>

<gadget id="calculator">5 / 8</gadget>
<output>5/8 = around 0.625</output>

<gadget id="calculator">(5/8) * (1/5)</gadget>
<output>1/8 = around 0.125</output>

<gadget id="calculator">1 - (5/8) - (1/8)</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">30 / (1/4)</gadget>
<output>120</output>
