Решение:

  1. $$40:8+2 \cdot 100 = 5 + 2 \cdot 100 = 5 + 200 = 205$$
  2. $$40:(8+2) \cdot 100 = 40:10 \cdot 100 = 4 \cdot 100 = 400$$
  3. $$(40:8+2) \cdot 100 = (5+2) \cdot 100 = 7 \cdot 100 = 700$$
  4. $$100-(40+36): 4 = 100 - 76 : 4 = 100 - 19 = 81$$
  5. $$(100-40+36): 4 = (60+36):4 = 96:4 = 24$$
  6. $$100-(40+36:4) = 100 - (40 + 9) = 100 - 49 = 51$$
  7. $$900:9-6 \cdot 10 = 100 - 6 \cdot 10 = 100 - 60 = 40$$
  8. $$600: 100+ 50 \cdot 10 = 6 + 50 \cdot 10 = 6 + 500 = 506$$
  9. $$70 \cdot 5+3 \cdot 100 = 350 + 3 \cdot 100 = 350 + 300 = 650$$
