2. perform fundamental operations on integers Learning Task 1 On a separate sheet of paper, illustrate a sea with the follow ing: a crab 5ft. below sea level, a cliff 3 ft. above the sea level, and a flying bird 4 ft. above sea level. Use a vertical number line to help you out in the illustration. After making the drawing, study it carefully and answer the questions below. 1. What Number might be a good representation for the sea level? 2. How do represent the distance below and above the sea level? 3. How far is the cliff from the sea level? 4. How far is the bird from the sea level? 5. How far is the crab from the sea level? 6. What is the distance between the cliff and the crab? 7. What is the distance between the bird and the crab? D The absolute value of a number, n ), is the distance of the given number on the number line from zero. The absolute value of a number disregards the direction from where it lies wit respect to zero. When we talk of distance, it is always positive. The absolute value of two, written as|2, represents its distance from 0 on the number line. Illustrative Example 1. Represent | 6 on the number line, 국 2 4 -2 -1 0 1 3 5 6 is 6 units from 0. Thus, the absolute value of 6 is 6, that is, 161-6​
