<gadget id="calculator">1 / 3</gadget>
<output>1/3 = around 0.333333</output>

<gadget id="calculator">(1/3) * 60</gadget>
<output>20</output>

<gadget id="calculator">20 - (1/3)</gadget>
<output>59/3 = around 19.666667</output>

<gadget id="calculator">19 + (59/3)</gadget>
<output>116/3 = around 38.666667</output>

<gadget id="calculator">1 + (1/3)</gadget>
<output>4/3 = around 1.333333</output>

<gadget id="calculator">(116/3) / (4/3)</gadget>
<output>29</output>

<gadget id="calculator">60 - 29</gadget>
<output>31</output>

<gadget id="calculator">(116/3) / (4/3) / 31</gadget>
<output>29/31 = around 0.935484</output>

<result>29/31 = around 0.935484</result>
