Math question: What is the sum of the digits in the number 7866?

To find the sum of the digits in the number 7866, we break it down into its constituent digits - 7, 8, 6, and 6. Adding them together, we get 7 + 8 + 6 + 6 = 27. So, the sum of the digits in 7866 is 27.

Math question: How many different ways can the number 7866 be arranged?

To find the number of different arrangements of the digits in the number 7866, we consider it a permutation problem. Since all digits are distinct, the number of arrangements is given by the formula n! / (n1! * n2! * ... * nk!), where n is the total number of digits, and n1, n2, ... nk are the number of occurrences of each digit. In this case, there are four digits (n = 4) and three 6's (n1 = 3). Thus, the number of arrangements is 4! / (3! * 1!) = 4. Therefore, there are four different ways in which the digits in the number 7866 can be arranged.

Math Question: What is the sum of the digits of the number 7866?

To find the sum of the digits, we add each digit in the number: 7+8+6+6 = 27.
