Question: What is the sum of the digits of the number 769?

To find the sum of the digits of a number, we add all the individual digits together. So for the number 769, the sum is 7 + 6 + 9 = 22.

Math question: What is the sum of the digits of the square root of 769 minus the product of the first 2 prime numbers?

To find the square root of 769, we get approximately 27.751. Summing its digits, 2 + 7 + 7 + 5 + 1 equals 22. The first 2 prime numbers are 2 and 3. Their product is 6. Subtracting 6 from 22 gives 16, which is the answer. Thus, the difference between the sum of the digits of the square root of 769 and the product of the first 2 primes is 16.

Question: What is the sum of the consecutive numbers from 1 to 769?

To find the sum, we can use the arithmetic series formula: S = (n/2)(first term + last term), where S denotes the sum, n represents the number of terms. In this case, since the first term is 1 and the last term is 769, and the number of terms is 769, we can substitute these values into the formula. Hence, the sum S = (769/2)(1 + 769) = 769(770)/2 = 296,385. Therefore, the sum of the consecutive numbers from 1 to 769 is 296,385.
