<output>2/3 = around 0.666667</output>

<gadget id="calculator">1 / 100</gadget>
<output>1/100 = around 0.01</output>

<gadget id="calculator">0.6 / (2/3) / (1/100)</gadget>
<output>90</output>

<gadget id="calculator">4.56 * 90</gadget>
<output>410.4</output>

<gadget id="calculator">410.4 + 0.6</gadget>
