Comparing absolute values 2

The  exercise appears under the 6th grade (U.S.) Math Mission. This exercise practices comparing numbers with absolute values.

Types of Problems
There are three types of problems in this exercise.


 * 1) Order the following values from least to greatest: This problem gives the user a set of numbers, some of them including absolute value brackets. The user is asked to order these numbers from least to greatest by dragging the numbers around.Capture2.png
 * 2) Which of the following are possible values for x?: This problem gives an inequality and a section of possible answers. The user is asked to find out which of the answers are possible values for x. Capture3.png
 * 3) Use the following number line to determine if the expressions are true or false.: This problem gives a number line with two points: a and b. This problem also gives some expressions to describe the relationship between a and b. The user is asked to see if these expressions are either true or false.Capture4.png

Strategies

 * 1) It is important to remember how absolute value brackets work. The absolute value of a number may be thought of as its distance from zero. In mathematics, the absolute value (or modulus) x of a real number x is the non-negative value of x without regard to its sign.

Real-life Applications

 * 1) Absolute values are used in physics and calculus to define certain situations, i.e. you want to know how far something traveled when it went 5 ft. one way and 5 ft. back.
