<gadget id="calculator">200 + 150</gadget>
<output>350</output>

<gadget id="calculator">65 / 100</gadget>
<output>13/20 = around 0.65</output>

<gadget id="calculator">1 - (13/20)</gadget>
<output>7/20 = around 0.35</output>

<gadget id="calculator">350 / (7/20)</gadget>
<output>1_000</output>

<result>1_000</result>
