Math question: What is the sum of the digits of the number 1844?

To find the sum of the digits, we add the individual digits together. The number 1844 has four digits (1, 8, 4, and 4). So, 1 + 8 + 4 + 4 = 17. Therefore, the sum of the digits of 1844 is 17.

Math question: How many three-digit numbers are divisible by the sum of their digits?

To find the number of three-digit numbers divisible by the sum of their digits, we start by considering the range from 100 to 999. We observe that the sum of digits of a three-digit number cannot be greater than 27 (9+9+9). Further, a number is divisible by its sum of digits if their ratio is an integer. Thus, our task is to determine the count of numbers from 100 to 999 that meet this criterion. To find these numbers, we iterate through each three-digit number and compute the sum of its digits. If the number is divisible by this sum, we increment our count. Finally, the total count will provide the desired answer. Now, let's calculate the count of three-digit numbers divisible by their sum of digits. Our algorithm starts by initializing the count to zero. Then, we iterate through all three-digit numbers from 100 to 999. For each number, we sum its digits. If the number is divisible by this sum, we increment the count. After executing this algorithm, the count of three-digit numbers divisible by their sum is the answer.

Math question: How many 3-digit numbers are divisible by 4 that are greater than or equal to 1844?

To find the answer, we need to determine how many 3-digit numbers are divisible by 4. The first 3-digit number divisible by 4 is 100, and the last is 996. To find the number of terms in this arithmetic sequence, we can use the formula: n = (last term - first term)/common difference + 1. Here, the common difference is 4 and the first term is 100, so n = (996-100)/4 + 1 = 221. However, we are only interested in the numbers greater than or equal to 1844. So, we need to find the number of terms starting from 1844 to 996. Considering that 1844 is not divisible by 4, we can take the next multiple of 4, which is 1848. Now, applying the formula, n = (996-1848)/4 + 1 = 38. Therefore, there are 38 3-digit numbers divisible by 4 that are greater than or equal to 1844.
