<gadget id="calculator">2 / 7</gadget>
<output>2/7 = around 0.285714</output>

<gadget id="calculator">84 * (2/7)</gadget>
<output>24</output>

<gadget id="calculator">84 - 24</gadget>
<output>60</output>

<gadget id="calculator">1 / 2</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">1 - (2/7) - (1/2)</gadget>
<output>3/14 = around 0.214286</output>

<gadget id="calculator">60 / (3/14)</gadget>
<output>280</output>
