-9,999,999,999 or, if dealing only with positive integers, 1,000,000,001
11 - if you mean lowest 2 digit odd number, as 10 is even.
The smallest two-digit odd number is 11. It is the first odd number that falls within the range of two-digit numbers, which start from 10.
1000/10 = 100
To find the number of five-digit odd numbers where the leftmost digit cannot be zero, we consider the structure of a five-digit number: ABCDE. The leftmost digit (A) can be any digit from 1 to 9 (9 choices). The last digit (E) must be odd, which gives us 5 choices (1, 3, 5, 7, or 9). The middle three digits (B, C, D) can each be any digit from 0 to 9 (10 choices each). Thus, the total number of such five-digit odd numbers is (9 \times 10 \times 10 \times 10 \times 5 = 45000).
There cannot be a proper three digit number between 10 and 20. It must be a two digit number. If you consider a 2-digit number between 10 and 20, then its tens digit MUST be 1 and so MUST be odd. So most of this question is either wrong or irrelevant. Are you sure you have not cut and pasted bits from two questions?

10. Any number can be squared or cubed.
