smallest number - 105680

To find the smallest number arrange the digits in ascending order.

greatest number - 986510

To find the greatest number arrange the digits in descending order.

3. Roman numeral for (856 - 102 = 754)

DCCLIV

754 = 500 + 100 + 100 + 50 + 5 − 1

500 = D

100 = C

50 = L

5 = V

1 = I

4. A number is divisible by 11 when the difference between sums of the digits in odd and even places is zero or a multiple of 11.

94556

Odd - 9 + 5 + 6 = 20

Even - 4 + 5 = 9

Difference - 20 - 9 = 11

11 is a multiple of 11 thus 94556 is divisible by 11.
