有一批零件由甲乙两人合作完成，原计划甲比乙多做50个，结果乙实际做的比计划少70个，比甲实际做的总数的(3/5)多10个，这批零件共有多少个？
<gadget id="calculator">70 * 2</gadget>
<output>140</output>

<gadget id="calculator">10 + 50 + 140</gadget>
<output>200</output>

<gadget id="calculator">3 / 5</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">1 - (3/5)</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">200 / (2/5)</gadget>
<output>500</output>

<gadget id="calculator">500 * 2</gadget>
<output>1_000</output>

<gadget id="calculator">1_000 - 50 - 140</gadget>
<output>810</output>
