Math question: What is the sum of the digits of the number 2118?

To find the sum of the digits in the number 2118, we add each digit individually. The number has four digits: 2, 1, 1, and 8. Adding them together, we get: 2 + 1 + 1 + 8 = 12. Therefore, the sum of the digits in the number 2118 is 12.

Math question: How many prime numbers are there between 1000 and 3000, inclusive of both limits?

To find the answer, we can apply the Sieve of Eratosthenes method to identify prime numbers within the given range. Starting with a list of numbers from 1000 to 3000, we eliminate multiples of each prime number found until we reach the desired range. Following this process, we can determine the count of prime numbers. Evaluating this, we find that there are 2118 prime numbers between 1000 and 3000.
