Math question: What is the sum of the digits of the number 3988?

To find the sum of the digits, we need to separate each digit and add them together. The number 3988 can be written as 3000 + 900 + 80 + 8. Thus, the sum is 3 + 0 + 0 + 0 + 9 + 0 + 8 + 0 + 8 = 28.

Math question: Find the sum of the digits of the number 3988 and divide it by the number obtained when reversing the digits. Subtract the result of dividing the sum of the digits by the number itself. Multiply this difference by 200.

The sum of the digits of 3988 is 3+9+8+8 = 28. Reversing the digits, we get 8893. Dividing the sum of digits by the reversed number gives 0.00316. Subtracting 0.00316 from the original number gives 3987.9968. Multiplying this difference by 200 results in 797,599.36.

Math question: What is the sum of all the digits in the number 3988?

To find the sum of the digits in the number 3988, we add each individual digit together. Hence, 3 + 9 + 8 + 8 equals 28.
