Sure! To show the operation (-7) + (-2) + (+6) on a number line, you can follow these steps:
1. Start at 0 on the number line.
2. Move 7 units to the left to represent -7.
3. From -7, move 2 more units to the left to represent -2.
4. Finally, from -9, move 6 units to the right to reach the final sum of -3.
So, the final result of the operation (-7) + (-2) + (+6) is -3, which is the point you will land on when you follow these steps on the number line.
