Answer 2

Ответ:

1)270

2)436

3)357

4)82

Answer 3

250 + 40 ÷ 2: First, we need to perform the division operation, 40 ÷ 2, which equals 20. Then, we add 250 and 20 together. Therefore, 250 + 40 ÷ 2 equals 270.

440 - 80 ÷ 20: First, we need to perform the division operation, 80 ÷ 20, which equals 4. Then, we subtract 4 from 440. Therefore, 440 - 80 ÷ 20 equals 436.

60 * 6 - 90 ÷ 30: First, we need to perform the division operation, 90 ÷ 30, which equals 3. Then, we multiply 60 and 6 together, which equals 360. Finally, we subtract 3 from 360. Therefore, 60 * 6 - 90 ÷ 30 equals 357.

80 ÷ 40 + 20 * 4: First, we need to perform the division operation, 80 ÷ 40, which equals 2. Then, we multiply 20 and 4 together, which equals 80. Finally, we add 2 and 80 together. Therefore, 80 ÷ 40 + 20 * 4 equals 82.
