Distance between numbers on a number line
The distance between two numbers on a number line is the absolute value of the difference between the two numbers. The distance can be found by subtracting the smaller number from the larger number and taking the absolute value of the result. The absolute value function makes negative numbers positive, ensuring the distance is always a positive value.
Examples:
- Find the distance between 3 and 8 on a number line.
Distance = |8 - 3| = |5| = 5
- Determine the distance between -4 and 7 on a number line.
Distance = |7 - (-4)| = |7 + 4| = |11| = 11
- Calculate the distance between -9 and -2 on a number line.
Distance = |-2 - (-9)| = |-2 + 9| = |7| = 7
By understanding how to calculate the distance between numbers on a number line, you can effectively visualize and interpret the magnitude of differences between values. Remember to subtract the smaller number from the larger number and take the absolute value of the result to find the distance between them on a number line.
