Math question: What is the sum of the digits of the number 7347?

To find the sum of the digits of the number 7347, we add each digit individually. The digit 7 is in the thousands place, the digit 3 is in the hundreds place, the digit 4 is in the tens place, and the digit 7 is in the ones place. Therefore, the sum is 7 + 3 + 4 + 7 = 21.

Math Question: Find the sum of the first and last digits of the number 7347.

To find the sum of the first and last digits of the number 7347, we can break it down as follows: the first digit is 7, and the last digit is 7 as well. Adding these two digits together, we get 7 + 7 = 14. Therefore, the sum of the first and last digits of the number 7347 is 14.

Math question: How many prime numbers are there between 1 and 7347?

To find the number of prime numbers between 1 and 7347, we can use the Sieve of Eratosthenes algorithm. Starting with the list of numbers from 2 to 7347, we eliminate all multiples of 2, then repeat the process for the next remaining number, which is 3. Continuing this iteration until reaching the square root of 7347, we are left with a list of prime numbers: {2, 3, 5, 7, 11, 13, 17, 19, 23, ...}. Counting all the prime numbers in the list, we find that there are 779 primes between 1 and 7347.
