Answer: [tex]=-17[/tex]
Step-by-step explanation:
The first thing you must remember is the mulplication of signs. You know that:
[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]
You can observe that the number inside the parentheses is positive (+) and the sign that is outside the parentheses is negative (-), therefore, when you multiply these signs you get a negative sign (-). Then you get:
[tex]-6-(11)=-6-11[/tex]
Now, you need to add these numbers. And the result obtained is:
[tex]=-17[/tex]
