105. 8 + 0 + 0 + 6 8 – 0 + 0 × 6 9 – 0 – 6 × 1 9 + 0 + 6 : 1 0:7+0·5+3 7:7-0·(4+2)

Решение:

1. 8 + 0 + 0 + 6 $$ 8 + 0 + 0 + 6 = 14 $$
2. 8 – 0 + 0 × 6 $$ 8 - 0 + 0 \times 6 = 8 - 0 + 0 = 8 $$
3. 9 – 0 – 6 × 1 $$ 9 - 0 - 6 \times 1 = 9 - 0 - 6 = 3 $$
4. 9 + 0 + 6 : 1 $$ 9 + 0 + 6 : 1 = 9 + 0 + 6 = 15 $$
5. 0:7+0·5+3 $$ 0 : 7 + 0 \cdot 5 + 3 = 0 + 0 + 3 = 3 $$
6. 7:7-0·(4+2) $$ 7 : 7 - 0 \cdot (4 + 2) = 1 - 0 \cdot 6 = 1 - 0 = 1 $$
