7.2-(1.1/1.1+6)=0.2

(2.3+1.8)*2-1.5=6.7

(8*9)/4-(5+6+7)=0

(1.1-1.1)+ (7.2 / 6) = 0,2
第2個唔識
((7-5) - (8/4)) / 9 = 0

(2.3 1.8)x2-1.5 = 6.7

1.1 1.1 6 7.2 = 0.2

7.2 -(1.1 /1.1) - 6 =0.2

---------------------------------------------------
2.3, 2, 1.8, 1.5 =6.7

((2.3 + 1.8) * 2) - 1.5 = 6.7
-------------------------------------------------

4 5 7 8 9 = 0

(4 + 5) / 9 + 7 - 8 = 0

等於69777471。
