Math Question: What is the sum of the digits of the number 7255 when each digit is squared, multiplied by its position value, and then added together?

To solve the question, first, square each digit of the number 7255: 7^2 = 49, 2^2 = 4, 5^2 = 25, 5^2 = 25. Now, multiply each squared digit by its position value: 49 × 1000 (position of 7) = 49,000, 4 × 100 (position of 2) = 400, 25 × 10 (position of first 5) = 250, 25 × 1 (position of second 5) = 25. Finally, add all the results together: 49,000 + 400 + 250 + 25 = 49,675. Hence, the sum of the digits of the number 7255, when each digit is squared, multiplied by its position value, and then added together, is 49,675.

Math question: Find the sum of the digits of the number 7255.

To calculate the sum of the digits in the number 7255, we break it down as follows: 7 + 2 + 5 + 5 = 19. Therefore, the sum of the digits in the number 7255 is 19.

Math question: If the number 7255 is divided by the sum of its digits, how many times does the resultant quotient contain the digit 5?

To solve the question, we first need to find the sum of the digits of 7255, which is 7 + 2 + 5 + 5 = 19. Now, divide 7255 by 19, resulting in 381 with a remainder of 16. Notice that the quotient, 381, does not contain the digit 5. However, we can divide the remainder, 16, by the sum of its own digits, which is 1 + 6 = 7. Thus, the quotient for this division is 2. Finally, combining the quotient from the first division (381) and the quotient from the second division (2), we have 3812. Notably, the digit 5 appears once in this final quotient. Therefore, the resultant quotient contains the digit 5 only once.
