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

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
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
