1 is the smallest whole number
The smallest whole number where the sum of the digits is 21 is 189. This number has a digit sum of 1+8+9 = 18. To find the smallest number with a digit sum of 21, we need to increase the hundreds digit by 1 and decrease the units digit by 1, resulting in 198.
-999
The answer to the smallest possible value of the sum of all the digits is 1. the number can either be 100 or 1000 - either way the sum is still one.
102.
101 is the smallest 3 digit odd whole number
Assuming that 000001 isn't considered as the smallest number with 6 digits on the basis that it would just be written as 1 instead: greatest whole number with 5 digits: 99,999 smallest whole number with 6 digits: 100,000 So hence the 6 digit number is the greatest. If negative numbers were involved though, then the 5 digit number would be the largest by definition. As it would still be 99,999 whereas the smallest 6 digit number would be -999,999
