Well let's see here, there is:
1.) 11
2.) 12
3.) 13
4.) 14
5.) 21
6.) 31
7.) 41
So the answer would be seven (7) numbers.
There are 10 digits in our number system. The symbols 0,1,2,3,4,5,6,7,8,and 9 are the digits used to create numbers.
It is 120 if the digits cannot be repeated.
There are 3,265,920 numbers that can be formed using all the digits. The answer to the question will depend on which one of these.
Numbers formed should be of at least 3 digits means they may be of 3 digits, 4 digits, 5 digits or 6 digits. There are 6 choices for digit in the units place. There are 5 and 4 choices for digits in ten and hundred’s place respectively. So, total number of ways by which 3 digits numbers can be formed = 6.5.4 = 120 Similarly, the total no.of ways by which 4 digits numbers can be formed = 6.5.4.3 = 360. the total no. of ways by which 5 digits numbers can be formed = 6.5.4.3.2 = 720. The total no.of ways by which 4 digits numbers can be formed = 6.5.4.3.2.1 = 720. So, total no.of ways by which the numbers of at least 3 digits can be formed = 120 + 360 + 720 + 720 = 1920.
There are 27 such numbers.

There are 27 such numbers.
yes,number system contains digits..
36
6*6*3 = 108 numbers.
There is only one number which contains 4 significant digits.
There are 2000 such numbers.
There are 2000 such numbers.
The number 1234567890 can create about 39 of 40 4 digit numbers.
