Answer 2

Let's calculate the expressions step by step:

1. 250 × 2 + 150 × 2 = 500 + 300 = 800

2. 490 + 330 + 150 = 820

3. 1000 - 490 × 2 = 1000 - 980 = 20

4. 1000 - (330 + 400) = 1000 - 730 = 270

So, the results are as follows:

1. 250 × 2 + 150 × 2 = 800
2. 490 + 330 + 150 = 820
3. 1000 - 490 × 2 = 20
4. 1000 - (330 + 400) = 270
