Answer 1

1. (11+2) x 10 + 8= 
(11+2)= 13
13x10=130
130 + 8= 138
2. 10+12 x (2+3)=
(2+3)=5
10+12=22
22x5=70
3. (10+2) x (7+3)=
(10+2)=12
(7+3)=10
12x10=120
4. (10÷2+5) x 3=
(10÷2+5)=10
10x3=30
5. (5-3+8) x 4-20=
(5-3+8)=10
10x 4-20=20
6. 22-8÷2x4-6= 0
7. (-1/2x1/4)2=
(-1/2x1/4)=-0.125
8. (3.5-7+2.5) (2-4)3=6
(3.5-7+2.5)=-1
(2-4)3=-6
9. (5x3x12) ÷ (-7+4-9+3)=
(5x3x12)=180
 (-7+4-9+3)=-9
180/-9=-20
10. (2+7-6)2 ÷ (-2x3)3= 
(2+7-6)2=6
(-2x3)3=-18
6/-18=-3
11. (-5+4-3) (-4) ÷ (-8+5-7)=
(-5+4-3)=-4
(-8+5-7)=-10
-4/-10=-1.6
