2. RESPOSTA
Percorrendo a trilha com as quatro operações
9x8 = 72 : 8 = 9 + 16 = 25
:
3 x 27 = 9 x 3 = 2 - 5 = 5
=
81 : 9 = 9 + 26 = 35 : 7 = 5
+
30 = 10 + 20 = 5 x 4 = 8 : 32 = 27
:
15 = 2 x 14 = 28 : 4 = 7 x 9 = 63
:
3 x 40 = 11 - 51 = 30 + 21 = 3
=
120 : 6 = 20 - 14 = 6 x 9 = 54
:
19 = 5 : 95 = 5 + 90 = 5 x 18 = 3
-
6 = 13 + 8 = 21 : 7 = 3 x 27
=
90 = 27 + 63 = 7 x 9 = 9 : 81
:
5 = 18 x 7 = 126 : 6 = 21 + 74 = 95
:
133 = 7 x 19 = 5
