Answer 2

It looks like you want to perform some calculations with given expressions. Let's break it down step by step:

1. Evaluate the expression inside each set of parentheses.

   • For the first set of parentheses: 79 - 649 = -570
   • For the second set of parentheses: 21 - 159 = -138

2. Substitute the results back into the original expression:

   • -(10, -570) - (0, -138)

3. Perform the remaining calculations:

   • -(-560) - (-138)
   • 560 + 138
   • 698

So, the value of the expression −(10,79−649)−(0,21−159)​ is 698.
