Answer 2

To evaluate the expression, let's follow the order of operations, which states that you should perform any calculations inside parentheses first, then evaluate exponentiation, followed by multiplication and division from left to right, and finally addition and subtraction from left to right.

The expression you provided is: 2 - 1^2 - 5 - 1 + 1

First, let's evaluate the exponentiation: 1^2 = 1

Now the expression becomes: 2 - 1 - 5 - 1 + 1

Next, perform the subtraction and addition from left to right: 2 - 1 = 1 1 - 5 = -4 -4 - 1 = -5 -5 + 1 = -4

Therefore, the final result of the expression 2 - 1^2 - 5 - 1 + 1 is -4.
