How many three digit numbers can be formed using 01234?

48 of them if digits may not be repeated. 100 if they can.


How many 3 digit numbers can be formed from the digits 0 through 9 in a set of three?

If the digits can be used more than once, then 900. If not, then 648.


What is the largest possible product of three 3 digit numbers all of whose digits are different?

Forming three three digit numbers that use the numbers 1-9 without repeating, the highest product possible is 611,721,516. This is formed from the numbers 941, 852, and 763.


How many different three digit numbers can be formed from the digits 0 through 9 if the first digit must be odd and the last digit must be even?

5 x 10 x 5 = 250 different numbers, assuming there is no limit to each digits' use.


How many 2-digit or 3-digit numbers can be formed using the digits 134568 and 9 which are diisible by 4?

48. Assuming no digit can be used more than once, the two digit numbers divisible by 4 are: 16, 36, 48, 56, 64, 68, 84, 96 8 of them. For any number to be divisible by 4, only the last two digits need be divisible by 4; so for three digit numbers, each of the two digit numbers above can be preceded by any of the remaining 5 digits and still be divisible by 4. → 5 x 8 = 40 three digit numbers are divisible by 4 → 40 + 8 = 48 two or three digit numbers made up of the digits {1, 3, 4, 5, 6, 8, 9} are divisible by 4. If repeats are allowed, there are an extra 2 two digit numbers (44 and 88) and each of the two digit numbers can be preceded by any of the 7 digits, making a total of 7 x 10 + 10 = 80 two and three digits numbers divisible by 4 make up of digits from the given set.
