Math question: What is the sum of the digits in the number 2138?

To find the sum of the digits in the number 2138, we first separate the digits from each other. The number 2138 can be expressed as 2 + 1 + 3 + 8. Adding these digits, we get 14 as the sum. Thus, the sum of the digits in 2138 is 14.

Math question: What is the sum of the digits of the number 2138?

To find the sum of the digits of 2138, we add up each digit individually. The digits in 2138 are 2, 1, 3, and 8. Adding them together: 2 + 1 + 3 + 8 = 14. Therefore, the sum of the digits of the number 2138 is 14.

Math question: How many even numbers are there between 1000 and 2138, inclusive?

To find the number of even numbers between 1000 and 2138, we first determine the first and last even numbers within this range. The first even number greater than or equal to 1000 is 1000 itself. The last even number smaller than or equal to 2138 is 2138 if it is even, or 2137 if it is odd. To check if 2138 is even, we can divide it by 2, which gives a remainder of 0, indicating that 2138 is indeed even. Now, we subtract the first even number from the last even number and divide the result by 2, since the numbers are consecutive even integers. (2138 - 1000) / 2 = 569. Hence, there are 569 even numbers between 1000 and 2138, inclusive.
