Question

Раскыв скобки:34,4-(18,1-5,6)+(-11,9+8)

Answer 1

34,4-18,1+5,6-11,9+8= 18

Answer 2

34,4-18,1+5,6-11,9+8=18

Answer 3

To simplify the expression and remove the parentheses, 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 is: 34.4 - (18.1 - 5.6) + (-11.9 + 8)

Step 1: Solve the expression within the parentheses:

18.1 - 5.6 = 12.5

Step 2: Replace the expression with its simplified form:

34.4 - 12.5 + (-11.9 + 8)

Step 3: Continue with addition and subtraction:

34.4 - 12.5 = 21.9

Step 4: Simplify the addition within parentheses:

(-11.9 + 8) = -3.9

Step 5: Replace the expression with its simplified form:

21.9 - 3.9

Step 6: Finally, perform the subtraction:

21.9 - 3.9 = 18

The final result is 18.
