Math question: Find the sum of all even numbers between 9885 and 10000.

To find the sum of all even numbers between 9885 and 10000, we can first identify the first and last even numbers in this range. The first even number is 9886, and the last even number is 9998. Next, we calculate the total number of even numbers in this range by subtracting the first even number from the last even number and adding 2 (since there are two additional even numbers, 9886 and 9998, that need to be included). So, the total number of even numbers is (9998 - 9886) + 2 = 114. To find the sum of these even numbers, we can use the formula for the sum of an arithmetic series: Sum = (number of terms / 2) * (first term + last term) = (114 / 2) * (9886 + 9998) = 57 * 19884 = 1,132,628. Therefore, the sum of all even numbers between 9885 and 10000 is 1,132,628.

Math question: What is the sum of the digits in the number 9885?

To find the sum of the digits, we add each digit individually: 9 + 8 + 8 + 5 = 30. Therefore, the sum of the digits in the number 9885 is 30.

Math question: If 9885 is multiplied by 5 and then divided by 2, what is the result?

When the number 9885 is multiplied by 5, it gives 49425. Dividing 49425 by 2 yields the result of 24712.5, making it the final answer.
