Answer 1

a) 9+1+9=19
(9+9):9+9=18:9+9=2+9=11
b) 8+1-8=1
(8+8):8-8=16:8-8=2-8=-6
8+8:(8-8)=8+8:1=8+8=16
c)6*6-6=36-6=30
3*(2*6-12:2)=3*(12-6)=3*6=18
(3*2*6-12):2=(36-12):2=24:2=12
d)3*5+20=15+20=35
12:4*(5+10*2)=3*(5+20)=3*25=75
e)0+24=24
2*3*4*(0+24)=24+24=48
f)100+50=150
10*(10+10*10):2=10*110:2=1100:2=550

Answer 2

a)9+9:9+9=
9+1+9=19
(9+9):9+9=
18:9+9=
2+9=11

b)8+8:8-8=
8+1-8=1
(8+8):(8-8)=
16:0=0

c)3x2x6-12:2=
36-6=30
[(3x2x6)-12]:2=
(36-12):2=
24:2=12

d)12:4x5+10x2=
3x5+20=15+20=35
(12:4)x(5+10)x2=
3x15x2=45x2=90

e)2x3x4x0+24=
0+24=24
(2x3x4)x(0+24)=
24x24=576

f)10x10+10x10:2=
100+100:2=
100+50=150

10x(10+10)x(10:2)=
10x20x5=200x5=1000
