Math Question: What is the sum of all the prime numbers less than or equal to 977?

To find the sum of prime numbers up to 977, we start by identifying the primes between 1 and 977. By employing a prime number generating method, we find that the primes in this range are {2, 3, 5, 7, 11, ..., 971}. Now, we can calculate their sum by adding all these prime numbers together. When we do so, we get 50295. Hence, the sum of all prime numbers less than or equal to 977 is 50295.

Math question: What is the sum of all three-digit numbers formed by permuting the digits of 977?

To find the sum of all three-digit numbers formed by permuting the digits of 977, we can use the method of finding permutations. The number 977 has three distinct digits, which can be rearranged in 3! = 6 ways (977, 979, 797, 799, 797, 977). To calculate the sum, we add up each permutation by considering the possible values in each digit place. The ones place can be either 7 or 9, resulting in a sum of (7 + 9) x 111 = 1776. For the tens place, we have three possible values: 7, 7, and 9. So, the sum becomes (7 + 7 + 9) x 10 = 230. Finally, for the hundreds place, there are two options: 7 or 9. This gives us (7 + 9) x 100 = 1600. Combining these results, the total sum is 1776 + 230 + 1600 = 3606.

Math question: What is the sum of all the digits in the number 977?

To find the sum of the digits in 977, we add the individual digits together. The digit 9 + the digit 7 + the digit 7 equals 23. Therefore, the sum of the digits in the number 977 is 23.
