Answer 2

Sure, I'd be happy to help you with these mathematical expressions:

1. (3 × (-2)) × 5 = -6 × 5 = -30
2. (-9 × 4) × (-2.5) = -36 × (-2.5) = 90
3. (13 × (-5)) × 20 = -65 × 20 = -1300
4. (-9 × 15) × (-2) = -135 × (-2) = 270
5. (-8 × (-12)) × 5 = 96 × 5 = 480
6. (3 × (-25)) × 2 = -75 × 2 = -150
