Math Question: What is the sum of the digits in the number 636?

To find the sum of the digits in the number 636, we add each individual digit together. The first digit is 6, the second digit is 3, and the third digit is also 6. Adding them together, we get 6 + 3 + 6 = 15. Therefore, the sum of the digits in the number 636 is 15.

Math question: Find the sum of all even numbers between 1 and 636.

To find the sum of even numbers between 1 and 636, we first determine the number of even numbers in this range. We divide 636 by 2, obtaining 318.5. Since the range only considers whole numbers, this means there are 318 even numbers in this range. Next, we find the first even number, which is 2. The last even number is 636. Now, we can use the formula for the sum of an arithmetic series: Sn = n/2 (a + l), where Sn represents the sum, n denotes the number of terms, a represents the first term, and l is the last term. Plugging in the values, we have Sn = 318/2 (2 + 636) = 159 * 638 = 101,442. Therefore, the sum of all even numbers between 1 and 636 is 101,442. Note: This assumes the range includes both 1 and 636, and we consider 1 as the first even number.

What is the sum of the digits in the number 636?

To find the sum of the digits in the number 636, we add each individual digit: 6 + 3 + 6 = 15. So, the sum of the digits in 636 is 15.
