Answer 1

-2-8-3 = ...

ответ - 7

Answer 2

Let's evaluate the expression step by step:

1. First, let's square -2: (-2)^2 = (-2) * (-2) = 4

2. Next, multiply 4 by 2: 4 * 2 = 8

3. Now, subtract 8 from 3: 3 - 8 = -5

So, the correct result is -5, not -9. The correct evaluation of the expression is: -2^2 - 4 * 2 + 3 = -5.
