Math Question: What is the sum of all the digits in the number 918?

To find the sum of the digits in the number 918, we separate the digits (9, 1, 8). Adding these digits, we get 9 + 1 + 8 = 18. Therefore, the sum of the digits in the number 918 is 18.

What is the sum of all the digits in the number 918?

The number 918 is composed of three digits, namely 9, 1, and 8. To find the sum of these digits, we add them together: 9 + 1 + 8 = 18. Therefore, the sum of the digits in the number 918 is 18.

Question: What is the sum of all the odd numbers from 1 to 918, inclusive?

To find the sum, we can use the arithmetic series formula: Sn = (n/2)(first term + last term) where Sn represents the sum of the arithmetic sequence and n is the number of terms. In this case, the first term is 1, the common difference is 2, and the last term can be found by solving the equation 1 + (n-1)2 = 918. Simplifying this equation gives n = 460, so the last term is 1 + (460-1)2 = 919. Now substituting these values, we get Sn = (460/2)(1 + 919) = 230 * 920 = 211,600. Therefore, the sum of all odd numbers from 1 to 918 is 211,600.
