The image shows a
Large Number Line Wall Display designed for educational purposes. It includes both positive and negative numbers, as indicated by the text "INCLUDES NEGATIVES!" and the range mentioned at the bottom:
-30 to 120. The display is part of the "Classic Black Collection" and is labeled as "editable," suggesting that users can customize it.
Key Features of the Number Line:
1.
Positive Numbers: The top section shows positive integers starting from 0 and extending to at least 11 (as visible in the image).
2.
Negative Numbers: The bottom section shows negative integers, starting from -3 and extending further to the left.
3.
Range: The number line includes numbers from
-30 to 120, covering a wide range of values.
4.
Design: The design is clean and simple, with circles marking each integer on the number line. The black circles highlight specific numbers (e.g., 0 and 10).
Problem-Solving Context:
Since the task involves solving a problem using this number line, let's assume the problem is related to basic arithmetic operations or understanding number placement. For example:
#### Example Problem:
Find the result of \( 7 - 4 \) using the number line.
#### Solution:
1.
Start at 7: Locate the number 7 on the number line.
2.
Move Left by 4 Units: Since subtraction involves moving left on the number line, move 4 units to the left from 7.
- From 7, move to 6 (1 unit left).
- From 6, move to 5 (2 units left).
- From 5, move to 4 (3 units left).
- From 4, move to 3 (4 units left).
3.
Result: After moving 4 units to the left from 7, you land on
3.
Thus, \( 7 - 4 = 3 \).
General Explanation:
The number line is a visual tool that helps in understanding:
- Addition: Moving right on the number line.
- Subtraction: Moving left on the number line.
- Positive and negative numbers: Understanding their placement relative to zero.
If the problem involves different operations or numbers, the same principles apply. Simply locate the starting number and move accordingly based on the operation (addition or subtraction).
Final Answer:
If the problem was \( 7 - 4 \), the solution is:
\[
\boxed{3}
\]
