Assuming that the first digit can't be zero:
If repetition of digits is permitted: (5 x 6 x 6) = 180 numbers of 3 digits.
If repetition of digits is not permitted: (5 x 5 x 4) = 100 numbers of 3 digits.

How many seven-digit telephone numbers are possible if the first two digits cannot be ones or zeros?
That makes:* 8 options for the first digit * 8 options for second digit * 10 options for the third digit * ... etc. Just multiply all the numbers together.
How many possible 5 digit combinations are there using 5 digits?
Possible 5 digit combinations using 5 digits only 1 time is 5! or 5*4*3*2*1 or 120. Using 5 digits where numbers can be used 5 times is 55 or 3125.
How many 4 digit numbers can be formed by the digits 1234567890?
The number 1234567890 can create about 39 of 40 4 digit numbers.
What is the smallest six digit number using the digits 012345?
012345 or -543210, if negative numbers are permitted.

What is the largest 6 digit number that you can make using the digits 012345?
543,210. If you can use them all multiple times, then it is 555,555.
How many possible 3 digit numbers can be made using the digits 604?
There are 4 possible numbers if the digits are not repeated; 18 if they are. Those are 3-digit numbers, assuming that zero would not be a leading digit. If zero is allowed for a leading digit, then you can have 6 for the non repeated, and 27 if repetition.
How many numbers are there between 100 and 999 in which all three digit numbers are different?
There are 9 possible numbers for the first digit (one of {1, 2, ..., 9}); with 9 possible digits for the second digit (one of {0, 1, 2, ..., 9} which is not the first digit)); with 8 possible digits for the third digit (one of {0, 1, 2, ..., 9} less the 2 digits already chosen); This there are 9 × 9 × 8 = 648 such numbers.
How many different 3-digit numbers less than 500 can be made using the digits 345 and 6 if the digits can be only used only once?
There are 2 possible digits for the first digit (3 or 4), leaving 3 possible digits for the second digit (5 and 6 and whichever was not chosen for the first), leaving 2 possible digits for the third. Thus there are 2 × 3 × 2 = 12 possible 3 digit numbers.
What is the probability of three digit numbers without repeated digits with numbers 0123456?
It is possible to create a 3-digit number, without repeated digits so the probability is 1.
How many digits can be the product of two digit numbers have to give examples to support your answer?
It can have 4 digits, because the highest possible two digit numbers 99*99=9801.
How many 4 digit numbers are possible with no two numbers being adjacent?
There are 2941 4-digit numbers such no two of its digits differ by 1.
How many 5 digit numbers are there with distinct digits?
There are 30,240 different 5-digit numbers. Math: 10*9*8*7*6 1st digit has 10 possible choices (0-9) 2nd digit has 9 possible choices (one of the digits was used in the 1st digit) 3rd digit has 8 possible choices 4th digit has 7 possible choices 5th digit has 6 possible choices
How many 4-digit numbers are possible if the hundreds digit is 8 and if repetition of digits is allowed?
-4
How many different three digit numbers can you form using the digits 1 2 3 5 6 7 and 9 without repetition?
There are seven possible digits for the first digit and 6 digits for the second (minus one digit for the digit used as the first digit) and 5 options for the last digit (minus one again for the second digit) and then you just multiply them all together to get a total possible combination of 210 numbers that are possible.
