Understanding Distance on a Number Line

The video tutorial explains how to calculate the distance between two numbers on a number line. It covers the concept of using subtraction to find the distance, emphasizing the importance of absolute value to ensure a positive result. The tutorial provides examples to illustrate the process and highlights the equivalence of subtracting in either order when using absolute value. The video concludes by discussing the practical application of this concept in mathematics.

What is the convention used to determine which number is greater on a number line?

• The number with a smaller absolute value is greater.

• The number with a larger absolute value is greater.

• The number on the right is greater.

• The number on the left is greater.

How do you calculate the distance between two numbers if you know which one is greater?

• Subtract the smaller number from the larger number.

• Add the two numbers.

• Divide the larger number by the smaller number.

• Multiply the two numbers.

What should you do if you don't know which of two numbers is greater when calculating distance?

• Add the numbers and take the absolute value.

• Multiply the numbers and take the absolute value.

• Divide one by the other and take the absolute value.

• Subtract one from the other and take the absolute value.

What is the distance between -2 and 3 on a number line?

• 6

• 5

• 4

• 3

If you subtract a smaller number from a larger number, what kind of value should you expect?

• An undefined value

• A negative value

• Zero

• A positive value

What is the absolute value of -5?

• 10

• -5

• 0

• 5

What happens to the distance calculation if you switch the order of subtraction?

• The distance remains the same.

• The distance doubles.

• The distance becomes zero.

• The distance becomes negative.

What is the result of taking the absolute value of a positive number?

• A negative number

• The same positive number

• Zero

• A larger positive number

Why is it important to understand the concept of distance between numbers?

• It helps in solving algebraic equations.

• It is crucial for understanding geometry.

• It is a fundamental concept in mathematics.
