Math question: How many four-digit numbers are there that are divisible by 11?

To find the solution, we need to determine the range of four-digit numbers divisible by 11. The smallest four-digit number divisible by 11 is 1001 (11 x 91) and the largest is 9999 (11 x 909). Now, we calculate the number of terms in this arithmetic sequence using the formula: number of terms = (last term - first term) / common difference + 1 In this case, the first term (1001) and the common difference (11) are known. So, subtracting 1001 from 9999 and dividing the result by 11, we get 818. Adding 1, we find that there are a total of 819 three-digit numbers divisible by 11 from 1001 to 9999. Thus, there are 819 four-digit numbers divisible by 11 in the range from 1001 to 9999.

Math question: What is the sum of the digits of the number 2449?
