there are 1000 buildings in a street. a sign - maker is contracted to number the houses from 1 to 1000. how many zeroes will he need? Choose the correct choice from the following options:
A) 190	B) 191	C) 192	D) 193	E) 194
<gadget id="calculator">1_000 / 10</gadget>
<output>100</output>

<gadget id="calculator">10 - 1</gadget>
<output>9</output>

<gadget id="calculator">9 * 10</gadget>

<result>C</result>
there are 1000 buildings in a street. a sign - maker is contracted to number the houses from 1 to 1000. how many zeroes will he need?
add(add(divide(1000, const_10), multiply(subtract(const_10, 1), const_10)), const_2)
divide as ( 1 - 100 ) ( 100 - 200 ) . . . . ( 900 - 1000 ) total 192 answer : c
