Answer 1

1
-2
5
вроде так
когда четное кол-во - тогда +

Answer 2

Let's solve these expressions step by step:

1. -(-(+1)): First, let's evaluate the expression inside the innermost parentheses, which is +1: -(-(+1)) = -(-(1)) Now, negate the number inside the innermost parentheses: -(-(1)) = -(-1) Finally, negate the result: -(-1) = 1

So, -(-(+1)) = 1.

2. -(-(-2)): Similarly, let's evaluate the expression step by step: -(-(-2)) = -(-(-2)) Negate the number inside the innermost parentheses: -(-2) = 2 Negate the result: -2

So, -(-(-2)) = -2.

3. -(-(-(-5))): Once again, let's evaluate the expression step by step: -(-(-(-5))) = -(-(-(-5))) Negate the number inside the innermost parentheses: -(-(-5)) = -(-5) Negate the result: -(-5) = 5

So, -(-(-(-5))) = 5.

Final results: -(-(+1)) = 1 -(-(-2)) = -2 -(-(-(-5))) = 5
