Answer 2

To evaluate the expression:

500 - 499 + 498 - 497 + 496 - 495 + ... + 2 - 1,

we can observe that the terms can be grouped into pairs as follows:

(500 - 499) + (498 - 497) + (496 - 495) + ... + (2 - 1).

Each pair has a difference of 1, so the sum of each pair is simply 1. Since there are 250 pairs (from 500 down to 2), we can multiply 1 by 250 to find the total sum:

1 * 250 = 250.

Therefore, the expression simplifies to 250.
