Выполним вычисления по порядку:

1. $$2 \cdot 3 - 10 - 60 = 6 - 10 - 60 = -4 - 60 = -64$$
2. $$5 \cdot 2 \cdot 3 + 70 = 10 \cdot 3 + 70 = 30 + 70 = 100$$
3. $$2 \cdot 4 \cdot 10 - 10 = 8 \cdot 10 - 10 = 80 - 10 = 70$$
4. $$(17 + 43) : 10 = 60 : 10 = 6$$
5. $$90 : (69 - 59) = 90 : 10 = 9$$
6. $$(84 + 16) : 10 = 100 : 10 = 10$$
7. $$1 \cdot (35 + 8) = 1 \cdot 43 = 43$$
8. $$0 \cdot (24 - 8) = 0 \cdot 16 = 0$$
9. $$(29 - 28) \cdot 6 = 1 \cdot 6 = 6$$
