Math question: How many times does the number 471 appear when counting from 1 to 10000?

To find the number of times 471 appears, we first calculate the total number of three-digit numbers from 100 to 999. The difference between the largest and smallest three-digit numbers is 999 - 100 + 1 = 900. Each of these numbers has exactly one hundred's place digit, meaning 471 will appear in the hundred's place 900 times. Next, we determine how many times 471 appears in the ten's and unit's place. In each of the hundred blocks (e.g., 100-199, 200-299, etc.), 471 appears twice: once as the hundred's place digit and once in the ten's and unit's place. Since there are 900 blocks of hundreds, 471 will occur an additional 900 times in the ten's and unit's place. Therefore, 471 appears a total of 900 + 900 = 1800 times when counting from 1 to 10000.

Question: If I divide a three-digit number by 7 and add 23, I get 89. What is the number?

Let's represent the three-digit number as 'xyz'. Given that (100x + 10y + z)/7 + 23 = 89, we can simplify to find 100x + 10y + z = 518. Since x can't be zero, we start by testing x = 1. With few iterations, we find x = 4, y = 7, and z = 1. Thus, the number is 471.

Math Question: What is the sum of the digits in the number 471?

To find the sum, we break down the number 471 into its digits: 4, 7, and 1. Then, we add these digits together: 4 + 7 + 1 = 12. Hence, the sum of the digits in 471 is 12. In general, to find the sum of digits in any given number, identify the digits and add them up.
