1) -3+7-2= 2

2) 5-9-4= -8

3) 12-17+2= -3

4) (-6) x (-3): [(-8):4}=(-6) x (-3) : (-2)= -9

5) (-2) x (5)- (-3) x (-6)+2 x (-4)=-10+3x (-6)-8=-10-18-8=-36

6) (-22): (11)- (12):(-3)+ (-8) x (2)= -2+4+16= 18

7) (135): (-15)+ (-24):(-8)-(-6)x(-1)=-9+3-6=-12

8) (-27);($3^{2}$)-(-5)x(-4)=$-3^{3}:3^{2}+ 5X(-4)$=-3+5x(-4)=-3-20=-23

9) $5^{2}$:(-2-3)+(-105+4+1):[(-2)x(-5)]= $5^{2}$:(-5)-100:10= -5-10=-15
10)$3^{41} :3^{38} -2^{16}:( 2^{3})^4$= $3^{3}-2^{16} :( 2^{3})^4$=27-$2^{4}$=27-16=11
