某校栽一批树，第一天栽了总数的(1/4)多10棵，第二天栽的棵数是第一天的2倍，第三天栽10棵刚好栽完，这批树共多少棵？
<gadget id="calculator">10 * 2</gadget>
<output>20</output>

<gadget id="calculator">10 + 20 + 10</gadget>
<output>40</output>

<gadget id="calculator">1 / 4</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">(1/4) * 2</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">1 - (1/4) - (1/2)</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">40 / (1/4)</gadget>
<output>160</output>

<result>160</result>
