Buna !

39 - 5 × (16 : 4 - 1) - 17 =

39 - 5 × (4 - 1) - 17 =

39 - 5 × 3 - 17 =

39 - 15 - 17 = 7

________________________

35 : [26 - 3 × (4 + 3)] =

35 : (26 - 3 × 7) =

35 : (26 - 21) =

35 : 5 = 7

________________________

[62 + 9 × (18 - 12 : 3 × 4)] : 5 =

[62 + 9 × (18 - 4 × 4)] : 5 =

[62 + 9 × (18 - 16)] : 5 =

(62 + 9 × 2) : 5 =

(62 + 18) : 5 =

(62 + 18) : 5 =

80 : 5 = 16

Bafta multa !
