Answer 2

320:8-30):2+(578:17+87):11=16

1)320:8=40

2)578:17=34

3)40-30=10

4)34+87=121

5)10:2=5

6)121:11=11

7)5+11=16

256*407-33078:298=104081

1)256*407=104192

2)33078:298=111

Answer 3

Let's break down the expression step by step:

1. Start with the first part: 320 / (-8) - 30

   320 / (-8) = -40 -40 - 30 = -70

2. Move to the second part: 578 / (17 - 87)

   17 - 87 = -70 578 / (-70) = -8.2571...

3. Finally, combine the results from steps 1 and 2 with the last part: -8.2571... / (-11)

   -8.2571... / (-11) = 0.7506...

So, the final result of the expression is approximately 0.7506.
