Cześć ;-)
60 : 3 · 2 = 20 · 2 = 40
10 - (12 - 4 + 2) = 10 - 10 = 0
4 · (5 - 3 + 2) = 4 · 4 = 16
[2 · (4 + 8 · 2) - 10] : 6 =
= [2 · (4 + 16) - 10] : 6 =
= (2 · 20 - 10) : 6 =
= (40 - 10) : 6 = 30 : 6 = 5
15 : 3 + 2 · (7 - 1) =
= 5 + 2 · 6 = 5 + 12 = 17
30 - 3 · [8 - 2 · (3 + 1)] =
= 30 - 3 · (8 - 2 · 4) =
= 30 - 3 · (8 - 8) = 30 - 3 · 0 = 30
Hasło → E U R O P A
