Answer:

1.18

2.23

3.62.625

4.9.72

5.19.625

6.15

7. -

8.597

9.24

10.30

Step-by-step explanation:

1.- 18÷6×3 = 9

- 12-3+9 = 18

2.- 12÷6 = 2

- 18-2+7 = 23

3.- 7×9 = 63

- 3÷8 = 0.375

- 63 - 0.375 = 62.625

4.- 8÷4×5 = 10

- 7÷25 = 0.28

- 10 - 0.28 = 9.72

5.- 90÷9×2 = 20

- 3÷8 = 0.375

- 20 - 0.375 = 19.625

6.(3² evaluate the power - 9) 3×[3+2×(10-9)] = 3×[3+2×1] = 3×[3+2] = 3×[5] = 15

7. -

8.- 120÷60 = 2

- 4×150 = 600

- 10 - 5 = 5

- 2+600-5 = 597

9. -2+5 = 3

- 5×5 = 25

- 24 - 25 = -1

- 8×3 = 24

10.- 39÷3 = 13

- 13 - 8 = 5

- 42÷7×5 = 30
