Answer 2

It appears that you have a mathematical expression that needs to be simplified. Let's break it down step by step:

1. (-3,25 - 2,75): This represents subtraction, so we subtract 2.75 from -3.25, which results in -6.00.

2. (-0,6): This is simply the number -0.6.

3. 0,8 - (-7): Here, you're subtracting the negative number -7 from 0.8. To do this, you can convert the subtraction of a negative number into addition: 0.8 + 7 = 7.8.

Now, let's combine all these results into the expression:

-6.00 - (-0.6) + 7.8

Now, you have two subtraction operations, and you can simplify them:

-6.00 + 0.6 + 7.8

Now, add the numbers:

-6.00 + 0.6 = -5.4 -5.4 + 7.8 = 2.4

So, the simplified result of the expression is 2.4.
