Because the third digit to the right indicates that the next order of magnitude position for that base is no longer blank.
Thus to the base 2 where there are two just digits 0 and 1 the magnitude works thus:-
0
1
10
11
100
101
110
111
1000
etc.
Meaningless question.
To find the two-digit counting numbers less than 30, we consider the numbers from 10 to 29, which gives us 20 two-digit numbers. The multiples of 20 that are two-digit numbers are 20. Since 20 is already included in the count of two-digit numbers less than 30, the total remains 20. Therefore, there are 20 two-digit counting numbers that are either less than 30 or a multiple of 20.
The smallest three digit number is 0.01. One less than that would be -1.01.
Not necessarily.

There are no three-digit numbers that equal 17. In fact, there are no numbers with more or less than two digits that equal 17. In fact, in the whole infinite supply of numbers, there is only one single number that equals 17. That number is . . . . . . . 17 .
Not sure what you're asking, but here are some examples of numbers that have a tens digit less than the ones digit: 13, 205, 1367, 29.632
three answers: 6849 or 4637 or 2425

The number can be any one of these four numbers:640751862973
Three numbers that fit these criteria are:108, 144, and 180.
