Answer 2

Let's calculate each expression step by step:

1. (90007-7):100-852:6 = (90000):100-852:6 [Subtract 7 from 90007] = 900-852:6 [Divide 90000 by 100] = 900-142 [Divide 852 by 6] = 758 [Subtract 142 from 900]

2. 142830-4002-152 = 142830-800-30 [Multiply 400 by 2] = 142030-30 [Multiply 15 by 2] = 142000 [Subtract 800 from 142830 and subtract 30]

3. 150:3+200*4+1000+2 = 50+800+1000+2 [Divide 150 by 3] = 852 [Add 50, 800, 1000, and 2]

4. 130*3+102000:100-184:2 = 390+1020-92 [Multiply 130 by 3] = 1318-92 [Divide 102000 by 100] = 1226 [Divide 184 by 2 and subtract 92]

Therefore, the results of the given expressions are:

1. (90007-7):100-852:6 = 758
2. 142830-4002-152 = 142000
3. 150:3+200*4+1000+2 = 852
4. 130*3+102000:100-184:2 = 1226
