9
I think the answer should be one - as they ask LEAST possible product
so 1x1 = 1 whereas the first answer was 9
9 times the number
You will get the greatest product if you choose the greatest possible numbers in both cases, i.e., 9 x 99.
10 because 10 is the first 2 digit number out of all numbers.
It is 891.
It can have up to 5 digits.
10
9 times the number
891 is the largest.

98,901
1000
99x9999=989901
It is 891.
9999 is the 4-digit number and 999 is the 3-digit 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
It can have up to 5 digits.
