Due to PEMDAS, you want to start with multiplying the parenthesis. I will group it first so that you can see the grouping easier.

-4(-2) + 3(4) + 3(-4) - 5(4)

Now we multiply the terms together.

-8 + 12 - 12 - 20

As you can see above, there is a positive 12 and a negative 12. These two will cancel out, leaving you with:

-8 - 20

Now you just combine the terms.

This results in a final answer of -28!
