Math question: What is the remainder when dividing 994 by the sum of its digits plus the product of its digits squared?

The sum of the digits of 994 is 9 + 9 + 4 = 22. The product of the digits squared is (9 x 9) x 4 = 324. Therefore, the divisor is 22 + 324 = 346. When 994 is divided by 346, the remainder is 296.

Math Question: What is the largest prime factor of the number 994?

In order to find the largest prime factor of 994, we need to factorize it. First, observe that 994 is even, so we can divide it by 2, resulting in 497. Now, continuing the process of dividing by primes, we find that 497 can be factored as 13 * 19 * 2. Hence, the largest prime factor of 994 is 19.

Math question: How many times does the number 994 appear when counting from 1 to 10,000 (inclusive)?

To find the answer, we can break down the counting process. From 1 to 999, there are 1000 numbers, and the number 994 appears once – so far, it has been counted once. Moving on to the next set of 1000 numbers (1000 to 1999), the digit 9 appears in the thousands place 100 times – but in each of those 1000 numbers, the digit 9 appears in the units place ten times. Therefore, the number 994 appears 1000 + 1000*10 = 11,000 times in the range 1 to 1999. Then, from 2000 to 2999, the digit 9 appears in the units place another 1000 times, bringing the total to 12,000 appearances. This pattern continues with each subsequent set of 1000 numbers until reaching 10,000, resulting in a total of 12,000 appearances of the number 994.
