What is the sum of the digits in the number 8439?

To find the sum of the digits in the number 8439, we need to add the individual digits: 8 + 4 + 3 + 9. The sum is 24.

Math question: What is the remainder when dividing 8439 by 14?

To find the remainder of 8439 divided by 14, we can perform the division: 8439 ÷ 14 = 602 remainder 7. Hence, the remainder is 7 when 8439 is divided by 14. This means that 8439 can be expressed as 602 groups of 14 plus an additional 7.

Math question: What is the result when 8439 is multiplied by the sum of its digits, divided by the difference between the largest and smallest digit, and then subtracted by the reverse of 8439?

To find the answer, we start by calculating the sum of the digits of 8439, which is 8 + 4 + 3 + 9 = 24. Next, we determine the difference between the largest and smallest digit, which is 9 - 3 = 6. Multiplying 8439 by the sum of its digits gives us 8439 × 24 = 202536. Dividing this result by the difference between the largest and smallest digit gives us 202536 ÷ 6 = 33756. Finally, we subtract the reverse of 8439, which is 9348, from 33756: 33756 - 9348 = 24408. Hence, the answer is 24408.
