Answer:
10,000
Step-by-step explanation:
In both 18,085 and 10,682, the greatest nonzero place value is the ten thousands place, so we should round each number to the nearest ten thousand. Remember that, when rounding a number, we want to look at the closest number above and below in the relevant place value. 18,085 and 10,682 are between the two ten thousands 10,000 and 20,000. 18,085 is closer to 20,000, so we round it up to that value, while 10,682 is closer to 10,000, so we round it down.
Finally, we take the difference of these rounded values to find a solution of 20,000 - 10,000 = 10,000, which is about 2500 off from the actual difference of 7403.
