Question

Вычислить2+2-4-5(6-8)=

Answer 1

2+2-4-5(6-8)=2+2-4-5(-2)=10

Answer 2

To compute the 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

Let's solve the expression step by step:

1. Calculate inside the parentheses: 6 - 8 = -2

2. Now the expression becomes: 2 + 2 - 4 - 5(-2)

3. Next, perform multiplication: -5 * (-2) = 10

4. The expression now becomes: 2 + 2 - 4 - 10

5. Finally, perform addition and subtraction from left to right: 2 + 2 = 4 4 - 4 = 0 0 - 10 = -10

The final answer is -10.
