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

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

<gadget id="calculator">150 * (7/6)</gadget>
<output>175</output>

<gadget id="calculator">150 + 175</gadget>
<output>325</output>

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