What is the sum of the digits in the number 2649?

To find the sum of the digits, we add each digit individually: 2 + 6 + 4 + 9 = 21.

Math question: How many even numbers are there between 1000 and 3000, inclusive?

To find the number of even numbers between 1000 and 3000, we need to determine the range and divide it by 2 since every other number is even. The difference between 1000 and 3000 is 2000. Dividing 2000 by 2 gives us 1000. Therefore, there are 1000 even numbers between 1000 and 3000, inclusive.

Math Question: What is the sum of the digits of the number 2649?
