Math question: How many different arrangements of the number 7257 can be formed using all four digits? (without repetition)

To find the number of arrangements, we'll calculate the number of permutations of the four digits (7, 2, 5, and 7). We have four positions to fill, so we'll consider a permutation formula: P(4,4) = 4! Now, since we have two identical digits (two 7's), we should divide by the number of ways these identical digits can be arranged amongst themselves. In this case, it would be 2!, as there are two 7's: P(4,4)/2! = 4!/2! = 4 × 3 × 2 × 1 / 2 × 1 = 12. Therefore, there are 12 different arrangements of the number 7257 that can be formed using all four digits.

Math question: What is the sum of the digits of the number 7257?

To find the sum of the digits, we add each digit individually. For the number 7257, we have 7 + 2 + 5 + 7 = 21. Therefore, the sum of the digits of 7257 is 21.

Math question: What is the sum of the digits in the number 7257?
