Question: What is the sum of all the digits in the number 3979?

To find the sum of the digits, we add each digit together. In the number 3979, the thousands place has a digit of 3, the hundreds place has a digit of 9, the tens place has a digit of 7, and the ones place has a digit of 9. Adding these digits together, we get 3 + 9 + 7 + 9 = 28. Thus, the sum of all the digits in the number 3979 is 28.

Math Question: If you multiply the number 3979 by the sum of its digits, subtract the product of its first and last digit, and then divide by its second digit, what is the result?

To solve this, we first find the sum of the digits: 3+9+7+9=28. Next, multiply 3979 by 28: 3979 * 28 = 111212. The product of its first and last digits is 3 * 9 = 27. Subtracting 27 from 111212, we get 111185. Finally, divide 111185 by the second digit (9): 111185 / 9 = 12354.44. Therefore, the result is approximately 12354.44.

Math question: What is the sum of the digits of the number 3979?

To find the sum of the digits in 3979, let's break it down into its individual digits: 3, 9, 7, and 9. Adding them together, we get: 3 + 9 + 7 + 9 = 28. Therefore, the sum of the digits in 3979 is 28.
