I would think the greatest 7 digit number would be 9,999,999. Therefore if you add 1 more, you would get 10,000,000. Makes sense to me anyway, lol.
10,003
Every square of a 4 digit number has more than four digits.
the greatest is bigger than the smallest
9 times the number
Rounding up implies the number is smaller than 1000. However, a number smaller than 1000 cannot be a 4-digit number. So there cannot be such a number. What was said is wrong. The greatest 4 digit number that rounds up is 999.9
10,003
1,000
