Question

( 8 x 9-4:2) - (91-9 x 9 ) =
100- (27+7 x 6 - 48:8 ) :7 =
(4x8 + 3 x 9 + 21) : 10: ( 40- 9 x 4 ) =
56 : (100 - 8 x 5 - 6 x 5 - 7 x 3-1) =
(24 + 6 x 2) : 4 + 7 - (28 - 12 : 3 ) : 6 =
(54 : 6 x 3 - 6 x 2 ) : 3 =
(2 x 3 x 3 ) : 2 x ( 45 : 9 + 72 : 8 - 16 : 2) =
4 x 3 + 15 - 7 x 2 + 37 - 8 x 6 =
19 + (6 x 7 - 18) - 2 x 9 =
73 - 58 + 29 - 4 =

Answer 1

(8*9-4:2)-(91-9*9)=(72-2)-(91-81)=70-10=60
10-(27+7*6-48:8):7=100-(27+42-6):7=100-(63:7)=100-9=91
(4*8+3*9+21):10:(40-9*4)=(32+27+21):10:(40-36)=80:10:4=2
56:(100-8*5-6*5-7*3-1)=56:(100-40-30-21-1)=56:(100-92)=56:8=7
(24+6*2):4+7-(28-12:3):6=(24+12):4+7-(28-4):6=36:4+7-24:6=9+7-4=12
(54:6*3-12):3=(9*3-12):3=(27-12):3=15:3=5
(2*3*3):2*(45:9+72:8-16:2)=18:2*(5+9-8)=9*6=54
4*3+15-7*2+37-8*6=12+15-14+37-48=2
19+(6*7-18)-2*9=19+(42-18)-18=25
73-58+29-4=40
