Answer 1

(- 2) + (+ 3).(- 3) =
(- 2) + (- 9) =
- 2 - 9 = - 11
---------------------------------------------------
(-5) - (+ 3).(- 2) =
(- 5) - (- 6) =
- 5 + 6 = 1 
--------------------------------------------------------------
(- 2) + (- 5).√16 =
(- 2) + (- 5).4 =
(- 2) + ( - 20) =
- 2 - 20 = - 22
------------------------------------------------------------------
 (- 6) - (- 6) + (- 2) =
- 6 + 6 - 2 = - 2
---------------------------------------------------------------
(- 3 + 4 - 2)² =
(- 1)² = 1
-------------------------------------------------------------------
( - 18) : ( - 2) + (+ 3) =
9 + 3 = 12
----------------------------------------------------
(- 9) - (+ 5) + (+1) = 
- 9 - 5 + 1 = - 13
-----------------------------------------------------------
(- 7) + (- 8) =
- 7 - 8 = - 15
---------------------------------------
(- 3)² = 9
