Math Question: If a number is multiplied by 911 and the product is divided by 911, what is the result?

When any number is multiplied by 911 and then divided by 911, it remains unchanged. This is because multiplying by 911 and dividing by 911 are inverse operations, so the number will be the same as the original number. Therefore, the result is the same number as that which was initially multiplied by 911.

Math Question: If you multiply the number 911 by the sum of its digits, subtract the product of its digits, and then divide by the difference between its tens digit and units digit, what is the resulting value?

To solve this, we start by finding the sum of the digits: 9 + 1 + 1 = 11. Next, we determine the product of the digits: 9 * 1 * 1 = 9. Then, we calculate the difference between the tens and units digit: 9 - 1 = 8. Now, let's proceed to the final step. Multiplying 911 by the sum of its digits results in 911 * 11 = 10,021. Subtracting the product of the digits gives us 10,021 - 9 = 10,012. Finally, dividing this by the difference between the tens and units digit gives us 10,012 / 8 = 1,251.5. Hence, the final value is 1,251.5.

Question: What is the sum of the digits in the number 911 squared, divided by its square root, multiplied by the factorial of the last digit, minus the largest prime number less than 911?

To solve this problem, we first calculate 911 squared, which equals 828721. Then, we find the square root of 828721, which is approximately 910.828. Next, we sum the digits of 828721, resulting in 20. The factorial of the last digit, 1!, is 1. We subtract the largest prime number less than 911, which is 907, from the previous result, giving us 20 - 907 = -887. Finally, we divide -887 by the approximate square root, 910.828, resulting in approximately -0.972. Therefore, the answer to the math question is approximately -0.972.
