Navigating the Number Line: A Step-by-Step Guide to Solving Kenneth's Problem

Understanding the Number Line

The number line is a fundamental concept in mathematics that represents the set of all real numbers in a linear order. It is a visual representation of numbers on a line, with positive numbers to the right of zero and negative numbers to the left. The number line is a powerful tool for understanding and visualizing mathematical concepts, including addition, subtraction, multiplication, and division.

Kenneth's Problem: From -3 to 7

Kenneth is working with the number line and needs to start at -3 and end at 7. To solve this problem, Kenneth must understand how to move from one point to another on the number line. The correct answer can be determined by analyzing the options provided.

Analyzing the Options

A. Add 10 to -3: This option suggests that Kenneth should add 10 to -3, resulting in 7. However, this is not the correct solution, as adding 10 to -3 would result in 7, but Kenneth needs to end at 7, not start at 7.

B. Add 7 to -3: This option suggests that Kenneth should add 7 to -3, resulting in 4. However, this is not the correct solution, as adding 7 to -3 would result in 4, but Kenneth needs to end at 7.

C. Subtract 10 from -3: This option suggests that Kenneth should subtract 10 from -3, resulting in -13. However, this is not the correct solution, as subtracting 10 from -3 would result in -13, but Kenneth needs to end at 7.

D. Subtract 7 from -3: This option suggests that Kenneth should subtract 7 from -3, resulting in 4. However, this is not the correct solution, as subtracting 7 from -3 would result in 4, but Kenneth needs to end at 7.

The Correct Solution

To solve Kenneth's problem, we need to find the correct option that will result in 7. Let's analyze the options again:

Option A: Add 10 to -3 = 7
Option B: Add 7 to -3 = 4
Option C: Subtract 10 from -3 = -13
Option D: Subtract 7 from -3 = 4

The correct solution is option A: Add 10 to -3. This is because adding 10 to -3 will result in 7, which is the end point that Kenneth needs to reach.

Conclusion

In conclusion, Kenneth needs to add 10 to -3 to get from the start point at -3 to the end point at 7. This solution is based on the correct analysis of the options provided and the understanding of how to move from one point to another on the number line.
