Math Question: How many times does the digit 2 appear in the numbers obtained by concatenating all integers from 1 to 923?

To find the number of times the digit 2 appears, we observe that each of the 100 consecutive numbers from 1 to 100 contains 20 twos at the tens place, while the remaining digits appear 10 times each. So, that accounts for 2,000 twos. Similarly, the same pattern repeats for numbers 101 to 200, 201 to 300, and so on, until 900 to 923. Each set of 100 contains 20 twos at the hundreds place, resulting in another 200 twos. Thus, the total number of twos is 2,200. Therefore, the digit 2 appears 2,200 times when all the numbers from 1 to 923 are concatenated.

Question: What is the product of 923 multiplied by the sum of its digits, divided by the difference between its digits?

To find the product of 923 multiplied by the sum of its digits, we first need to calculate the sum of the digits: 9 + 2 + 3 = 14. Next, let's calculate the difference between the digits, which is 9 - 2 = 7. Now, multiply 923 by 14: 923 * 14 = 12922. Finally, divide this result by 7: 12922 / 7 = 1846. Therefore, the answer is 1846.

What is the sum of the digits of the number 923?

The sum of the digits can be found by adding the individual values of each digit: 9 + 2 + 3 = 14. Thus, the sum of the digits of the number 923 is 14.
