1. 4x(-4)x(-5)= 80
2. 5x(-4)-2x(-5) = -10
3. [-4x(-5)]x2= 40
4. -4x2x(-5)= -13
5. 4x(-4)x(-5)x2= 160
6. 3x(-4)x(-5)-5x(-5)= 85
7. -4x(-5)÷2= 10
8. 3x(-4)x2÷4= -6
9. 5x(-5)-(-4)x2= -17

I wasn't sure what the space were so I thought they were mistakes and did the problems as if they were not there but if they were meant to be there then tell me what they were meant to be and I will fix it (If there is no spaces on yours then you are probably thinking that I am going crazy)
