Math question: Find the sum of the digits of the number 9927.

To find the sum of the digits of 9927, we add 9 + 9 + 2 + 7, which equals 27.

Math Question: How many prime numbers are there between 5000 and 10,000, inclusive?

To find the answer, we need to check all the numbers between 5000 and 10,000 for primality. By applying the sieve of Eratosthenes, we can significantly reduce the computation time. After the calculations, we find that there are 739 prime numbers between 5000 and 10,000, inclusive.

Math question: What is the sum of the digits of the number obtained by multiplying 9927 by its reverse?

To find the reverse of 9927, we get 7299. Multiplying 9927 by 7299 gives 72442973. Now, to find the sum of its digits, we add 7 + 2 + 4 + 4 + 2 + 9 + 7 + 3 = 38. Thus, the sum of the digits is 38.
