It is: 97*2 = 194
Zero.
121
least two-digit composite number = 11
10 because 10 is the first 2 digit number out of all numbers.
It is 1.
10
What is the least possible 6 digit odd number with only using 1 to 9 once
4 is the least one digit composite number
Since the 1-digit number is explicitly required to be positive but the 2-digit number is not so constrained, the obvious solution is to make the 2-digit number negative. This gives 9*(-99) = -891
10 is the smallest 2 digit number.

Assuming a seven digit whole number: 1,111,111. But if you have to use at least one (2) digit, then 1,111,112.
No.
The number 8 in that question is the number with the least amount of value (0.008).
Assuming a seven digit whole number: 1,111,111. But if you have to use at least one (2) digit, then 1,111,112.
The least 1 digit number that is composite is 4. It is because all numbers before that are prime.
