Answer 2

Let's simplify these expressions step by step:

1. 1 - 8 + (-12) + (-1 + (-9))

First, let's simplify within the parentheses:

1 - 8 + (-12) + (-1 - 9)

Now, add the numbers together:

(1 - 8) = -7 (-12) stays the same (-1 - 9) = -10

Now, add these results:

-7 + (-12) + (-10)

Next, combine the numbers:

-7 - 12 - 10

Now, add them all together:

-7 - 12 = -19 -19 - 10 = -29

So, the result of the first expression is -29.

2. (-38 + (-11)) + (-2 + (-29))

First, simplify within the parentheses:

(-38 - 11) + (-2 - 29)

Now, add the numbers together:

(-38 - 11) = -49 (-2 - 29) = -31

Now, add these results:

-49 + (-31)

Combine the numbers:

-49 - 31

Now, add them all together:

-49 - 31 = -80

So, the result of the second expression is -80.
