Well, darling, if you're looking to form three-digit numbers using the digits 0 to 9, you've got 10 choices for the first digit (can't start with 0, honey), 10 choices for the second digit, and 10 choices for the third digit. So, that's 10 x 10 x 10, which gives you a grand total of 1000 possible three-digit numbers. Hope that clears things up for you, sugar!
48 of them if digits may not be repeated. 100 if they can.
If the digits can be used more than once, then 900. If not, then 648.
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.
5 x 10 x 5 = 250 different numbers, assuming there is no limit to each digits' use.

27 three digit numbers from the digits 3, 5, 7 including repetitions.
I take it that you want to make three digits numbers with 8,7,3, and 6 without repetition. The first digit cane be selected from among 4 digits, the second from 3 digits, the third digit from 2, hence the number of three digit numbers that can be formed without repetition is 4 x 3 x 2 = 24

There are 900 three-digit numbers.

If the digits may not be repeated, there are 6x5x4x3x2x1 = 720 numbers, If digits can be repeated, the answer is 6x6x6x6x6x6 = 46,656 numbers If zero is ong the available digits but is excluded from the first place. 5x6x6x6x6x6=38,880 numbers
5 x 10 x 5 = 250 different numbers, assuming there is no limit to each digits' use.
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
757
24 three digit numbers if repetition of digits is not allowed. 4P3 = 24.If repetition of digits is allowed then we have:For 3 repetitions, 4 three digit numbers.For 2 repetitions, 36 three digit numbers.So we have a total of 64 three digit numbers if repetition of digits is allowed.
24+24+12+4=64.
