Math question: If the number 1021 is divided by 17, what is the remainder?

To find the remainder when 1021 is divided by 17, we need to divide 1021 by 17. 17 divides evenly into 1020 (17 x 60) leaving no remainder. Therefore, 1021 divided by 17 gives a remainder of 1.

Math question: What is the remainder when 1021 is divided by 7?

To find the remainder when 1021 is divided by 7, we can first determine the quotient by dividing 1021 by 7. The quotient is 145. Now, multiplying 145 by 7 gives us 1015. To find the remainder, we subtract 1015 from 1021, resulting in a remainder of 6. Therefore, when 1021 is divided by 7, the remainder is 6.

Math question: What is the sum of the digits in the number 1021 when each digit is squared and multiplied by its position in the number?

To find the sum, we square each digit: (1^1 * 1) + (0^2 * 2) + (2^3 * 3) + (1^4 * 4) = 1 + 0 + 16 + 4 = 21. Therefore, the sum of the squared digits multiplied by their positions in the number 1021 is 21. Explanation: First, we consider each digit in the number 1021 and calculate its square. The first digit is 1, and its square is 1. The second digit is 0, and since it is in the second position, we square it and multiply by 2, resulting in 0. The third digit is 2, and its square is 4, which we multiply by 3 since it is in the third position, resulting in 12. Finally, the fourth digit is 1, and since it is in the fourth position, we square it and multiply by 4, resulting in 4. Adding these values together, we get 1 + 0 + 12 + 4 = 21. Therefore, the sum of the squared digits multiplied by their positions in the number 1021 is 21.
