Math question: Find the sum of all prime numbers less than 379.

To find the sum of all prime numbers less than 379, we need to identify the prime numbers within this range. Starting from 2, we can use the Sieve of Eratosthenes or divide each number by all prime numbers less than its square root to determine its primality. After identifying the primes less than 379, we list them as follows: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, and 211. Next, we add up all these primes to obtain the sum: 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 + 31 + 37 + 41 + 43 + 47 + 53 + 59 + 61 + 67 + 71 + 73 + 79 + 83 + 89 + 97 + 101 + 103 + 107 + 109 + 113 + 127 + 131 + 137 + 139 + 149 + 151 + 157 + 163 + 167 + 173 + 179 + 181 + 191 + 193 + 197 + 199 + 211 = 4199. Therefore, the sum of all prime numbers less than 379 is 4199.

Question: What is the sum of the digits of the number 379?

The sum of the digits of the number 379 can be found by adding 3 + 7 + 9, which equals 19.

Math Question: A number is formed by rearranging the digits 3, 7, and 9 without repetition. What is the largest possible three-digit number that is divisible by 3?

To find the largest three-digit number divisible by 3, we can use divisibility rules. Since the sum of the digits (3+7+9 = 19) is not divisible by 3, we need to rearrange the digits. The largest possible number is 973. Checking its divisibility, we find that the sum of its digits (9+7+3 = 19) is not divisible by 3. We rearrange again to get 937. This number does meet the divisibility rule since the sum of its digits (9+3+7 = 19) is divisible by 3. Thus, the largest three-digit number formed by rearranging the digits 3, 7, and 9 is 937.
