Math question: What is the smallest prime number that can be formed by rearranging the digits of 2221, and when multiplied by 6 and divided by 3, the resulting quotient is equal to the sum of its digits multiplied by 13?

Rearranging the digits of 2221, we get 1122. Testing for primality, we divide it by primes up to the square root of 1122 and find that it is not divisible by 2, 3, 5, or 7. Therefore, 1122 is the smallest prime number that can be formed by rearranging the digits of 2221. When multiplied by 6, we get 6732. Dividing that by 3 gives us 2244, which is equal to the sum of its digits (2 + 2 + 4 + 4 = 12) multiplied by 13. Thus, 1122 satisfies the given conditions.

Math question: What is the sum of the digits in the number 2221?

To find the sum of the digits in the number 2221, we add the individual digits together. The digit '2' appears three times, and the digit '1' appears once. Adding these digits: 2 + 2 + 2 + 1 = 7. Therefore, the sum of the digits in 2221 is 7.

Math question: What is the sum of the digits of the number 2221?

To find the sum of the digits of the number 2221, we add the individual digits together. 2 + 2 + 2 + 1 = 7. So, the sum of the digits of the number 2221 is 7. The sum represents a collective value obtained by combining each digit. In this case, 2 appears three times, and 1 appears once. Adding these digits together yields a total of 7.
