Answer 3

To solve this expression, we'll perform the calculations step by step:

Step 1: -1.9 + (-3.5)

To add two negative numbers, we simply add their absolute values and keep the negative sign:

|-1.9| + |-3.5| = 1.9 + 3.5 = 5.4

Since both numbers were negative, the result will also be negative:

-1.9 + (-3.5) = -5.4

Step 2: -0.6 + (-1/2) + 0.7

First, let's combine the negative values:

-0.6 + (-1/2) = -0.6 - 0.5 = -1.1

Now, add 0.7 to the result:

-1.1 + 0.7 = -0.4

So, the final result is:

-1.9 + (-3.5) = -5.4 -0.6 + (-1/2) + 0.7 = -0.4
