(-7+3)4
-1(18-11)

Thank you!

3(2+8) → 3(10) → 30(-3+4)2 → (1)2 → 2-5(4-2) → -5(2) → -10(12+13)(-2) → (25)(-2) → -508(10-4) → 8(6) → 48(-4+-7)(-3) → (-11)(-3) → 33(-7+3)4 → (-4)4 → -16-1(18-11) → -1(7) → -7

The last digits/ values are the answers.

3(2+8)=30
(-3+4)2=2
-5(4-2)=-10
(12+13)(-2)=-50
8(10-4)=48
(-4+-7)(-3)=33
(-7+3)4=-16
-1(18-11)=-7
