Answer 1

Ответ:

8 + (−13) − (−11) - (-7) - 42 =

Разложим на действия:

1. 8 + (-13)= - (13 - 8) = -5
2. -5 - (-11) = 11 - 5 = 6
3. 6 - (-7) = 6 + 7 = 13
4. 13 - 42= - (42 - 13) = -29

Answer 2

To evaluate the expression, let's perform the calculations step by step:

8 + (-13) - (-11) - (-7) - 42

First, let's simplify the negative signs:

8 - 13 + 11 + 7 - 42

Next, let's perform the addition and subtraction from left to right:

-5 + 11 + 7 - 42

Now, let's continue the addition and subtraction:

6 + 7 - 42

Finally, perform the remaining addition and subtraction:

13 - 42

The result is -29. Therefore, the expression 8 + (-13) - (-11) - (-7) - 42 is equal to -29.
