<gadget id="calculator">4 / 3</gadget>
<output>4/3 = around 1.333333</output>

<gadget id="calculator">1 / 6</gadget>
<output>1/6 = around 0.166667</output>

<gadget id="calculator">(4/3) - (1/6)</gadget>
<output>7/6 = around 1.166667</output>

<gadget id="calculator">350 / (7/6)</gadget>
<output>300</output>

<gadget id="calculator">300 * (4/3)</gadget>
<output>400</output>

<result>400</result>
