一个绳子截去全长的(1/3)，再接上(1/2)米，正好是8米，绳子原来长多少米．
<gadget id="calculator">1 / 2</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">8 - (1/2)</gadget>
<output>15/2 = around 7.5</output>

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

<gadget id="calculator">1 - (1/3)</gadget>
<output>2/3 = around 0.666667</output>

<gadget id="calculator">(15/2) / (2/3)</gadget>
<output>45/4 = around 11.25</output>

<result>45/4 = around 11.25</result>
