-35

Sure! Here are the step-by-step calculations for each expression:

1. - (-23)
= 23
The negative sign in front of a negative number cancels out.

2. 11
= 11
There is no operation to perform here.

3. -11
= -11
Again, no operation to perform.

4. 35
= 35
No operation needed.

5. -35
= -35
No operation needed.

I hope this helps! Let me know if you have any further questions.

To find the answer to each of these expressions, we can follow the basic rules of arithmetic. Here's a breakdown for each expression:

1. - (-23):
To simplify this expression, we can think of the double negative as a positive. So, - (-23) becomes +23. Therefore, the answer is 23.

2. 11:
This expression is already a single number, so the answer is simply 11.

3. -11:
Again, this expression is already a single number, but it has a negative sign in front of it. So, the answer is -11.

4. 35:
Similarly, this expression is a single number. The answer is 35.

5. -35:
This expression is once again a single number with a negative sign in front of it. Therefore, the answer is -35.

Remember, when working with negative signs, a single negative sign in front of a number means it is negative, while two negative signs cancel each other out and become positive.
