Calculate with a simple algorithm: (1/4)/(3-(5/13)-(8/13))
用简便算法计算：(1/4)/(3-(5/13)-(8/13))
<gadget id="calculator">1 / 4</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">5 / 13</gadget>
<output>5/13 = around 0.384615</output>

<gadget id="calculator">8 / 13</gadget>
<output>8/13 = around 0.615385</output>

<gadget id="calculator">3 - (5/13) - (8/13)</gadget>
<output>2</output>

<gadget id="calculator">(1/4) / 2</gadget>
<output>1/8 = around 0.125</output>

<result>1/8 = around 0.125</result>
