2)440:22=20

3)20×(-13)=-260

4)57-260=-203

Answer 2

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

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

The expression you provided is:

Г)57-440:(-14-8)·(-13)

Step 1: Evaluate what's inside the parentheses:

-14 - 8 = -22

Step 2: Perform the division:

440 ÷ (-22) = -20

Step 3: Perform the multiplication:

-20 × (-13) = 260

Step 4: Finally, subtract the result from 57:

57 - 260 = -203

So, the final answer is -203.
