The diagram shows a vertical number line with an arrow starting at 8 and pointing downwards to 4. Then, another arrow extends from 4 down to -4.

To write an equation for this, let's break it down into two steps:

1. The first arrow represents subtraction, moving from 8 to 4. This is a drop of 4 units, so:
   \[
   8 - 4 = 4
   \]

2. The second arrow represents moving from 4 to -4, which is a drop of 8 units, so:
   \[
   4 - 8 = -4
   \]

Combining both steps into a single equation:
\[
8 - 4 - 8 = -4
\]

Alternatively, if you wanted to write this using addition:
\[
8 + (-4) + (-8) = -4
\]

Would you like more details on any part of this? Here are some related questions:

1. How do you convert subtraction to addition with negative numbers?
2. What are the rules for adding and subtracting integers?
3. How can you represent similar movements on a horizontal number line?
4. How does this apply to real-life scenarios like temperature changes?
5. Can you always combine several steps into one equation?

**Tip**: When adding or subtracting integers, always pay attention to the direction (positive or negative) and magnitude of movement on the number line.

Write an addition or subtraction equation to describe the diagram showing movement from 8 to 4 and then from 4 to -4 on a vertical number line.
