Math question: What is the sum of the digits of the number 9978?

To find the sum of the digits in the number 9978, we need to break it down. The first digit is 9, the second digit is 9, the third digit is 7, and the fourth digit is 8. Adding these digits together, we have 9 + 9 + 7 + 8 = 33. Hence, the sum of the digits in the number 9978 is 33.

What is the sum of all the digits of the number 9978?

To find the sum of the digits of 9978, we add each digit individually: 9 + 9 + 7 + 8 = 33.

What is the sum of all even numbers from 2 to 9978, inclusive?

To find the sum of all even numbers, use the formula for the sum of an arithmetic series: S = (n/2)(first + last), where n is the number of terms. In this case, n = 9978/2 = 4989, and the first even number is 2, while the last is 9978. Plugging these values into the formula, we get S = (4989/2)(2 + 9978) = 2494 * 9979 = 24,884,886. Therefore, the sum of all even numbers from 2 to 9978 is 24,884,886.
