Math question: What is the sum of all odd numbers from 1 up to the number 9917 (inclusive)?

To find the sum, we begin by calculating the total number of odd numbers. Since odd numbers are alternately spaced by two, we can use the formula (last - first)/2 + 1. For 9917, the formula becomes (9917 - 1)/2 + 1 = 4959. The next step is calculating the sum using the formula: sum = (first + last) * (total_numbers / 2). Substituting the values, we have sum = (1 + 9917) * 4959/2 = 4960 * 2479 = 12,274,240. Therefore, the sum of all odd numbers from 1 up to 9917 (inclusive) is 12,274,240.

Math question: What is the largest prime number less than 10000?

The largest prime number less than 10000 is 9973. A prime number is a number that is divisible only by 1 and itself. To find the largest prime number less than 10000, we start from 9999 and work our way backwards, checking each number for divisibility by other numbers. After eliminating the non-prime numbers through divisibility tests, we find that 9973 is the largest number that only divides by 1 and itself. Hence, 9973 is the answer to the given question.

Math question: What is the sum of the digits of the number obtained by multiplying 9917 with its largest prime factor?

To find the largest prime factor of 9917, we need to prime factorize it. Dividing 9917 by primes, we get 9917 = 9917 (which is a prime number). Thus, the largest prime factor is 9917 itself. Multiplying this with 9917 gives us 9917 * 9917 = 98339389. Now, to find the sum of the digits of this number, we add all the individual digits: 9 + 8 + 3 + 3 + 9 + 3 + 8 + 9 = 52. Therefore, the answer is 52.
