What is the sum of all integers from 1 to 378, inclusive?

The sum of all integers from 1 to 378 can be calculated using the formula for the sum of an arithmetic series: Sn = (n/2)(a1 + an), where Sn is the sum, n is the number of terms, a1 is the first term, and an is the last term. In this case, n = 378, a1 = 1, and an = 378. Plugging in these values, we have Sn = (378/2)(1 + 378) = 189 * 379 = 71731. Therefore, the sum of all integers from 1 to 378 is 71731.

Math question: If 378 is divided by 14, multiplied by 2, and then subtracted by 47, what is the result?

To find the result, first divide 378 by 14, which equals 27. Multiply 27 by 2 to get 54. Finally, subtract 47 from 54, resulting in 7. Therefore, the answer is 7. The whole process can be calculated as follows: (378 ÷ 14) × 2 - 47 = 27 × 2 - 47 = 54 - 47 = 7.

Math question: Find the sum of the digits of the number 378.

To find the sum of the digits of a number, we add up each individual digit. For the number 378, we have 3 + 7 + 8 = 18. Therefore, the sum of the digits of 378 is 18. In detail, we start by breaking down the number 378 into its component digits: 3, 7, and 8. Then, we add these digits together: 3 + 7 + 8 = 18. Thus, the sum of the digits of 378 is 18.
