Answer 1

(-3)(2)(-2)
(-6)(-2)
12

or 

(-3)(2)(-2)
(-3)(-4)
12

You get the same answer. 

Answer 2

The problem is    (-3) · (2) · (-2)

You know that when you're doing multiplication, the order
doesn't matter.  So let me line up the factors like this:

                                                      (-3) · (-2) · (2)  .

Multiply the first two of them:      (-3) · (-2)  =  +6
(The product is positive because
both factors have the same sign.)

Now multiply that result by the last factor:      (6) · (2)  =  12  .

What was so hard about that ?
