Question

80+80:80–80+8
10x[1+6x(4+4: 4)]
0: 6+0x6+6: 6+4: 4
(904: 8+136–97)x5
(29+29x29): (29–19)
5+5x[5+5x(5+5x5)]​

Answer 1

80+80:80-80+8=80+1-80+8=81-80+8=1+8=9

10×[1+6×(4+4:4)]=10×[1+6×(4+1)]=10×(1+6×5)=10×(1+30)=10×31=310

0:6+0×6+6:6+4:4=0+0+1+1=2

(904:8+136-97)×5=(113+136-97)×5=(249-97)×5= 152×5=760

(29+29×29):(29-19)=(29+841):10=870:10=87

5+5×[5+5×(5+5×5)]=5+5×[5+5×(5+25)]= 5+5×(5+5×30)=5+5×(5+150)=5+5×155=5+775= 780
