Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

P: Parentheses first E: Exponents (none in this expression) MD: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right)

Here's the step-by-step solution:

-1 - 1 - 1 + (9 × 38) + 345 - 555

Step 1: Calculate the multiplication within parentheses. 9 × 38 = 342

The expression becomes: -1 - 1 - 1 + 342 + 345 - 555

Step 2: Perform the addition and subtraction from left to right.

-1 - 1 = -2 -2 - 1 = -3 -3 + 342 = 339 339 + 345 = 684 684 - 555 = 129

The final result is 129.
