Find the sum of all even numbers between 1 and 2587, excluding 2587, and the sum of all odd numbers from 1 to 2587, including 2587. Then subtract the odd sum from the even sum.

The sum of even numbers is (2586/2)(2586/2 + 1) = 1681391, and the sum of odd numbers is (2587/2)(2587/2 - 1) + 2587 = 1681392. Subtracting these results, we get 1681391 - 1681392 = -1. Therefore, the result is -1.

What is the sum of the digits of 2587 when each digit is raised to the power of its position in the number and added together?

To find the sum, we have 2^1 + 5^2 + 8^3 + 7^4 = 2 + 25 + 512 + 2401 = 2940. Therefore, the sum of the digits of 2587 is 2940.

Question: If the number 2587 is multiplied by 3, and then divided by 9, what would be the remainder when dividing the result by 4?

To find the remainder, first multiply 2587 by 3, which equals 7761. Then, divide 7761 by 9 to get 862 with a remainder of 3. Finally, divide the remainder (3) by 4, which gives a remainder of 3. Therefore, the remainder when dividing 2587 * 3 by 9 and then by 4 would be 3.
