Math question: What is the largest prime number less than 9893?

To find the largest prime number less than 9893, we can start checking from the given number backward. Starting from 9893, the number 9892 is not a prime as it is divisible by 2. Similarly, 9891 is divisible by 13. Continuing this process, we discover that 9889 is the largest prime number less than 9893. It can be obtained by dividing 9893 by consecutive prime numbers (less than its square root) starting from 3. Thus, 9889 is the answer.

Math question: What is the sum of all the odd numbers from 1 to 9893?

To find the sum of odd numbers from 1 to 9893, we can use the formula for the sum of an arithmetic series. The first odd number is 1, and the last odd number less than or equal to 9893 is 9893 itself. So, there are (9893 - 1) / 2 + 1 = 4947 odd numbers in this range. Using the formula S = (n/2)(first term + last term), where S is the sum and n is the number of terms, we can calculate the sum. The first odd number is 1, and the last odd number is 9893. Plugging these values into the formula, we get S = (4947/2)(1 + 9893) = 12297411. Therefore, the sum of all the odd numbers from 1 to 9893 is 12,297,411.

What is the sum of all the digits in the number 9893?

To find the sum of all the digits in 9893, we add the individual digits together. The digit 9 appears twice, while the digits 8 and 3 appear once each. Adding them: 9 + 9 + 8 + 3 = 29. Therefore, the sum of all the digits in 9893 is 29.
