Where may this apply in a job?
You can use absolute value in almost any job, but it varies on what your doing. An example can be a nurse. A nurse has to figure out how much medication a patient has to take per day and how many times a day. Another example may be construction workers. The construction workers are given a $5,000 limit to build a bridge. So because of that limit, the constuction workers must find out how much it will cost to buy steel, bolts, and other stuff neccesary to build a bridge and be under or equal to their limit. You can use absolute value for any job, but it varies on the type or what your doing on the job.
