Math question: What is the sum of the digits of the number obtained by multiplying 1992 by the sum of the digits of 1992?

To find the sum of the digits of 1992, we have 1 + 9 + 9 + 2 = 21. Now, when we multiply 1992 by 21, we get 41,832. The sum of the digits in 41,832 is 4 + 1 + 8 + 3 + 2 = 18.

What is the sum of the prime factors of the number 1992?

To find the sum of prime factors of 1992, we need to factorize it. The prime factorization of 1992 is 2^3 × 3 × 83. Hence, the prime factors are 2, 2, 2, 3, and 83. When we sum them, 2 + 2 + 2 + 3 + 83 = 92. Therefore, the sum of the prime factors of 1992 is 92.

Math question: What is the sum of all odd numbers between 1000 and 1992, inclusive?

To find the sum of odd numbers between 1000 and 1992, we first need to determine the total count of odd numbers within this range. The first odd number in this range is 1001, and the last odd number is 1991. There are two ways to calculate the count: 1) By using the formula: count = [(last odd number - first odd number) / 2] + 1 = [(1991 - 1001) / 2] + 1 = 495 + 1 = 496 2) By considering that odd numbers occur in a sequence with a difference of 2. So, we can find the count by [(last odd number - first odd number) / 2] + 1 = [(1991 - 1001) / 2] + 1 = 495 + 1 = 496. Now, the sum of all odd numbers can be calculated using the formula for the sum of an arithmetic series: sum = (count / 2) * (first odd number + last odd number) = (496 / 2) * (1001 + 1991) = 248 * 2992 = 739,616. Thus, the sum of all odd numbers between 1000 and 1992 is 739,616.
