The little sloppy forgot to add 0 to the end of the product when calculating a multiplication with 0 at the end of the multiplier, and the result was 4005 less than the correct product. What is the correct product.
小马虎在计算一道乘数末尾有0的乘法时，忘记在积的末尾添上0，结果比正确的积少4005．正确的积是多少．
<gadget id="calculator">1 / 10</gadget>
<output>1/10 = around 0.1</output>

<gadget id="calculator">1 - (1/10)</gadget>
<output>9/10 = around 0.9</output>

<gadget id="calculator">4_005 / (9/10)</gadget>
<output>4_450</output>

<result>4_450</result>
