Пошаговое объяснение:

1)

(-(-17)) = 17

2)

-(-(+(-2))) = -2

3)

-(+(-63))​ = 63

Answer 2

Let's evaluate the given expressions step by step:

1. (-(-17)) To simplify this expression, we can remove the double negative sign. When we negate a negative number, it becomes positive. Therefore, (-(-17)) is equal to 17.

2. -(-(+(-2))) We can simplify this expression by applying the rules of negation. The negative sign in front of the expression (-2) can be distributed to the inner terms. So, -(-(+(-2))) is equivalent to -(-(2)). Again, we have a double negative. By removing the double negative, we get -(-(2)) = -2.

3. -(+(-63)) Similar to the previous expression, we can simplify this one by distributing the negative sign. The positive sign can be removed since it doesn't affect the value. Therefore, -(+(-63)) is equivalent to -(-63). Again, we have a double negative. By removing the double negative, we get -(-63) = 63.

To summarize:

1. (-(-17)) = 17
2. -(-(+(-2))) = -2
3. -(+(-63)) = 63
