Math Question: What is the sum of the digits of 8239 multiplied by its thousands place digit, divided by the tens place digit, and subtracted from its ones place digit squared?

To find the sum of the digits, we have 8 + 2 + 3 + 9 = 22. Multiplying this by the thousands place digit (8), we get 22 * 8 = 176. Dividing it by the tens place digit (3), we have 176 ÷ 3 = 58.67. Now, we subtract this from the ones place digit squared (9^2), which gives us 81 - 58.67 = 22.33.

Math question: What is the sum of the digits in the four-digit number 8239?

To find the sum of the digits, we add each digit individually. Starting from the left, we have 8 + 2 + 3 + 9 = 22. Hence, the sum of the digits in the number 8239 is 22.

Math question: If the number 8239 is multiplied by 7 and then divided by 3, what is the result?

To find the result, multiply 8239 by 7 to get 57673. Then divide 57673 by 3 to obtain 19224.3333333333333333333333 (approx). Thus, the result of multiplying 8239 by 7 and dividing by 3 is approximately 19224.3333333333333333333333.
