Answer 2

Let's solve each of these expressions step by step:

1. -3 + 4 + 67 + (-19) + (-44) + 34

First, add the positive numbers: -3 + 4 + 67 + 34 = 102

Now, add the negative numbers: -19 + (-44) = -63

Now, add the positive and negative results together: 102 + (-63) = 39

So, the result of the expression is 39.

2. 3 + (-2) - (-1)

First, simplify the double negative: 3 + (-2) + 1

Now, add the numbers together: 3 - 2 + 1 = 2

So, the result of the expression is 2.
