| Types of Problems: | 2 |
The Absolute value to find distance exercise appears under the 7th grade (U.S.) Math Mission. This exercise practices taking the absolute value of the difference of two numbers to find the distance between those numbers. Apply this principle to solve word problems.
Types of Problems[]
There is two types of problems in this exercise:
Find the absolute correct number line.
- 1. Select the number line that matches the expression: This problem has an absolute value equation and two number lines. This problem asks users to find the number line that correctly displays the absolute value.
Find the absolute value.
- 2. Find the expression that shows the distance between two numbers: This problem has two numbers. The user is asked to find which absolute value correctly matches those two numbers.
Strategies[]
Knowledge of absolute value and number lines are essential to ensure success in this exercise and get accuracy badges and speed badges.
- 1. The distance between two numbers on the number line is the absolute value of their difference.
Real-life Applications[]
- Absolute value can be used in applications connecting algebra to geometry.
- The absolute value function is an example of a continuous but non-differentiable function (specifically at zero).
- Absolute value extends into the concept of modulus for complex numbers.
