Problema 6
o saptamana are 7 zile
2 × 7 = 14 carabusi sunt intr-un salcam
3 × 14 = 14 + 14 + 14 = 42 furnici sunt in salcam
2 × 42 = 42 + 42 = 84 omizi
14 + 42 + 84 = 140 de insecte sunt in salcam
Problema 7
9 alune → luni
9 + 1 = 10 alune → marti
10 + 1 = 11 alune → miercuri
11 + 1 = 12 alune → joi
12 + 1 = 13 alune → vineri
13 + 1 = 14 alune → sambata
14 + 1 = 15 alune → duminica
9 + 10 + 11 + 12 + 13 + 14 + 15 = 84 alune a adunat intr-o saptamana
