Math question: What is the sum of the digits of the number 278?

To find the sum of the digits, we add each digit individually. In 278, we have 2 + 7 + 8 = 17. Therefore, the sum of the digits of 278 is 17. The sum of the digits represents the total value obtained by adding each digit of a number together. In this case, the digits of 278, namely 2, 7, and 8, are added together resulting in 17. This concept is often used in various mathematical computations, ranging from number theory to digital root calculations.

Math question: What is the remainder when 278 is divided by 9?

To find the remainder when 278 is divided by 9, we divide 278 by 9: 278 ÷ 9 = 30 with a remainder of 8. Therefore, the remainder when 278 is divided by 9 is 8.

Math question: What is the sum of the digits in the number 278?
