81:9+26*6-144:72=
4*18-9-32:8+111*8=
(25*3:15)*(48*2:16)=
(12*7:42)*(16*6:24)=

Answer 1

81 : 9 + 26 * 6 - 144 : 72 = 163

1) 81 : 9 = 9

2) 26 * 6 = 156

3) 144 : 72 = 2

4) 9 + 156 = 165

5) 165 - 2 = 163

4 * 18 - 9 - 32 : 8 + 111 * 8 = 947

1) 4 * 18 = 72

2) 32 : 8 = 4

3) 111 * 8 = 888

4) 72 - 9 = 63

5) 63 - 4 = 59

6) 59 + 888 = 947

(25 * 3 : 15) * (48 * 2 : 16) = 30

1) 25 * 3 = 75

2) 75 : 15 = 5

3) 48 * 2 = 96

4) 96 : 16 = 6

5) 5 * 6 = 30

(12 * 7 : 42) * (16 * 6 : 24) = 8

1) 12 * 7 = 84

2) 84 : 42 = 2

3) 16 * 6 = 96

4) 96 : 24 = 4

5) 2 * 4 = 8
