Math question: What is the sum of the digits of the number 7289?

To find the sum of the digits of the number 7289, we add the individual digits together. The digit 7 + 2 + 8 + 9 equals 26. Therefore, the sum of the digits of the number 7289 is 26.

Math question: What is the sum of the ones, tens, hundreds, and thousands digits in the number 7289?

To find the sum of the digits, we break down the number 7289. The ones digit is 9, the tens digit is 8, the hundreds digit is 2, and the thousands digit is 7. Adding these digits together: 9 + 8 + 2 + 7 = 26. Therefore, the sum of the ones, tens, hundreds, and thousands digits in the number 7289 is 26.

Question: What is the sum of the digits when the number 7289 is multiplied by 7 and divided by 8, then subtracted by the result when 2 is added to the number?

To solve this, we start by multiplying 7289 by 7, which equals 51023. Then, we divide this by 8, resulting in 6377.875. After rounding down to the nearest whole number, we get 6377. Now, if we add 2 to the original number, we have 7291. To find the final answer, we subtract 6377 from 7291, which gives us 915. Finally, we calculate the sum of its digits by adding 9 + 1 + 5, which equals 15. Therefore, the sum of the digits when the number 7289 is multiplied by 7 and divided by 8, then subtracted by the result when 2 is added to the number, is 15.
