3,36:3,2+(4-(7-6,3)*4,2)-11
First, let's simplify the expression inside the parentheses:

7 - 6.3 = 0.7
0.7 * 4.2 = 2.94

Now we can substitute this back into the original expression:

3,36:3,2 + (4 - 2.94) - 11
= 3,36:3,2 + 1.06 - 11
= 3,36:3,2 - 9.94

Now, let's subtract the two numbers:

3,36:3,2 = 3 - 2 = 1

Finally, we have:
1 - 9.94 = -8.94

Therefore, the simplified expression is -8.94.
