Answer 1

4+5+6-7+8-9=7

Answer 2

To get a result of 7 by placing either addition (+) or subtraction (-) symbols between the numbers 4, 5, 6, 7, 8, and 9, you can arrange the numbers as follows:

4 + 5 - 6 + 7 + 8 - 9 = 7

Let's check the calculation step by step:

1. 4 + 5 = 9
2. 9 - 6 = 3
3. 3 + 7 = 10
4. 10 + 8 = 18
5. 18 - 9 = 7

So, the expression "4 + 5 - 6 + 7 + 8 - 9" equals 7.
