To calculate the number of different 4-digit combinations that can be made using numbers 0 through 9, we use the concept of permutations. Since repetition is allowed, we use the formula for permutations with repetition, which is n^r, where n is the number of options for each digit (10 in this case) and r is the number of digits (4 in this case). Therefore, the number of different 4-digit combinations that can be made using numbers 0 through 9 is 10^4, which equals 10,000 combinations.
From left to right, pick the smallest possible digit every time. This will give you the smallest possible number.
Every square is a rectangle, but not every rectangle is a square.
Using the digits 12279, the largest number that can be represented is 97,221.
