Math question: What is the sum of the digits in the number 2779 when each digit is squared, multiplied by its corresponding place value, and then multiplied by 2?

To find the sum, we start by squaring each digit. For 2, we get 2² = 4, then we multiply by the place value (2 * 1000 = 2000) and multiply by 2 to get 4000. Similarly, for 7, we get 7² = 49, multiply by the place value (49 * 100 = 4900), then multiply by 2 to get 9800. For the remaining digits 7 and 9, we follow the same steps to get 9800 and 194000 respectively. Finally, we add all four values together: 4000 + 9800 + 9800 + 194000 = 217600. Thus, the sum of the digits in 2779, squared, multiplied by place value, and then by 2 is 217600.

Math question: If 2779 is divided by the product of its digits, what is the result?

To find the product of its digits, we multiply 2 x 7 x 7 x 9 = 882. Now, let's divide 2779 by 882. The quotient is approximately 3.14878.

Math question: What is the remainder when 2779 is divided by the sum of its digits?

To find the sum of the digits in 2779, we add 2 + 7 + 7 + 9 = 25. Now, when we divide 2779 by 25, we get a quotient of 111 and a remainder of 4. Therefore, the remainder when 2779 is divided by the sum of its digits is 4.
