7. 54 – (46 + 7) 37 – (24 – 8) (56 – 48) : 8 9 · 3 + 9 · 7 8 · 9 – 8 · 4 9 · 6 – 27 : 3 41 · 1 0 : 16 23 · 0

1) $$54 - (46 + 7) = 54 - 53 = 1$$

2) $$37 - (24 - 8) = 37 - 16 = 21$$

3) $$(56 - 48) : 8 = 8 : 8 = 1$$

4) $$9 \times 3 + 9 \times 7 = 27 + 63 = 90$$

5) $$8 \times 9 - 8 \times 4 = 72 - 32 = 40$$

6) $$9 \times 6 - 27 : 3 = 54 - 9 = 45$$

7) $$41 \times 1 = 41$$

8) $$0 : 16 = 0$$

9) $$23 \times 0 = 0$$
