<gadget id="calculator">10 / 100</gadget>
<output>1/10 = around 0.1</output>

<gadget id="calculator">66 * (1/10)</gadget>
<output>33/5 = around 6.6</output>

<gadget id="calculator">66 + (33/5) + 66</gadget>
<output>693/5 = around 138.6</output>

<gadget id="calculator">1 + (1/10)</gadget>
<output>11/10 = around 1.1</output>

<gadget id="calculator">(693/5) / (11/10)</gadget>
<output>126</output>
