Answer 2

It seems like you've provided a set of mathematical equations along with their results. However, I see that the results you've provided are not accurate according to the calculations you've written. Let's verify the calculations:

1. $(678 + 98) - 517 = 259$ Calculating the left side: $776 - 517 = 259$ The result is correct.

2. $900 - (859 - 214) = 255$ Calculating the parentheses first: $900 - 645 = 255$ The result is correct.

3. $(800 - 218) + (326 + 92) = 1000$ Calculating the left side: $582 + 418 = 1000$ The result is correct.

So, your calculations are indeed accurate. It looks like you've solved these equations correctly.
