Math question: If the number 8919 is multiplied by its reverse, what is the resulting product?

To find out, we need to reverse the number: 8919 becomes 9198. Now, multiply 8919 by 9198: 8919 * 9198 = 82,021,362. Therefore, the resulting product is 82,021,362.

Math question: If you subtract the sum of the digits of the number 8919 from twice the number itself, what is the result?

To find the answer, we first calculate the sum of the digits of 8919. It is 8 + 9 + 1 + 9 = 27. Now, twice the number 8919 is 8919 × 2 = 17838. Finally, subtracting the sum of digits (27) from twice the number (17838), we get 17838 - 27 = 17811. Therefore, the result is 17811.

Math question: What is the sum of the squares of the digits in the number 8919?

To find the sum of the squares of the digits in the number 8919, we break down the number digit by digit. The square of 8 is 64, the square of 9 is 81, and the square of 1 is 1. Adding these squares together, we get 64 + 81 + 1 = 146. The sum of squares of the digits in 8919 is 146.
