Math question: If 2109 is divided by 3, multiplied by 7, and then subtracted by 5, what is the result?

To find the result, we first divide 2109 by 3, which gives us 703. Next, we multiply it by 7 to get 4921. Lastly, we subtract 5 from that value, yielding 4916 as the final result. So, if we perform the operations of dividing by 3, multiplying by 7, and subtracting 5 on 2109, we obtain 4916 as the answer.

Math question: What is the sum of the digits in the number 2109?

To find the sum of the digits in 2109, we add each digit together. The number 2 + 1 + 0 + 9 equals 12.

Question: What is the sum of the digits when the number 2109 is multiplied by the number formed by reversing its digits?

To find the sum of the digits, we first need to calculate the product of 2109 and its reverse, which is 9012. Multiply them together: 2109 × 9012 = 19,000,308. To calculate the sum of the digits in 19,000,308, we start by adding the individual digits: 1 + 9 + 0 + 0 + 0 + 3 + 0 + 8 = 21. Hence, the sum of the digits when 2109 is multiplied by its reverse is 21.
