Math question: What is the sum of the digits of the number 8013?

To find the sum of the digits, we add up each individual digit: 8 + 0 + 1 + 3 = 12.

Question: Divide the number 8013 into two parts such that the first part is double the second part. What are the two parts?

Let the second part be x, then the first part would be 2x. Therefore, the equation becomes 2x + x = 8013. Simplifying further, we get 3x = 8013, and solving for x, we find x = 2671. Hence, the two parts are 2x = 5342 and x = 2671.

What is the sum of the digits of the number 8013 multiplied by the difference between 8013 and twice the sum of its digits?

To find the sum of the digits, we add 8 + 0 + 1 + 3 = 12. Twice the sum of the digits is 2 * 12 = 24. Now, we calculate the difference between 8013 and 24, which is 8013 - 24 = 7989. Finally, we multiply the sum of the digits (12) by the difference (7989) to get: 12 * 7989 = 95868. Thus, the answer is 95868.
