Use two methods to simplify the calculation: 26*(12/25)+(13/25).
用两种方法简算：26*(12/25)+(13/25)．
<gadget id="calculator">12 / 25</gadget>
<output>12/25 = around 0.48</output>

<gadget id="calculator">26 * (12/25)</gadget>
<output>312/25 = around 12.48</output>

<gadget id="calculator">13 / 25</gadget>
<output>13/25 = around 0.52</output>

<gadget id="calculator">(312/25) + (13/25)</gadget>
<output>13</output>

<result>13</result>
