What is the sum of all the four digit numbers formed using the digits 0 1 2 and 3 if repetition is allowed?

It is 415968.

How many different numbers can you form using all four numbers of 1 9 8 4?

The four digits can be used to produce infinitely many different numbers if repetition is permitted. Without repetition, there are 24 possible numbers. A lot more can be produced if the numbers are combined using binary oprations, fore example, 19 * 8/4 = 19*2 = 38.

How many four digit numbers can be formed from digits 1 2 3 4 if repeated is allowed and how many are odd numbers?

This is permutations with repetition. The answer is 4^4 = 256 total permutations. Since 2 of the digits used are odd (and 2 are even), then half of the possibilities will be odd: 128 odd numbers.

How many 4 number combinations can be made from four numbers?

If repetition is allowed and order is important, then you have essentially a base-4 number system, with the numbers ranging from 00004 to 33334. The quantity of permutations in this example is 44 = 256. If repetition is not allowed, but order is important, then it is 4! = 24. * * * * * The above answer is perfectly correct. But, as stated in the answer, for permutations. However, according to the mathematical definition of combinations (as opposed to permutations), the order is irrelevant to combinations. 1234 is the same as 1423 or 4213 etc. Consequently, there can be only one 4-number combination from 4 numbers

How many four digit numbers can be created using the digits 0 through 9?

If leading zeros are allowed, then you have 0000 through 9999 which is 10,000 numbers.If leading zeros not allowed: the smallest four-digit number is 1000, eliminating 0000 through 0999 (one thousand numbers are not allowed), so it is 9,000 numbers.
