Absolute Value and Integers
W
I
Lesson
After going through this module, you are expected to represent the absolute
value on a number line as the distance of a number from 0 and perform fun
damental operations on integers.
Learning Task 1: On a separate sheet of paper, illustrate a sea with the
following: 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?
Answers
Answer:
the value of the integer is w and I means integer
Answer:
1. Zero is the apt representation for sea level
2. The distance above sea level is represented by positive integers, while below by negative integers.
Step-by-step explanation:
1. Since sea level is considered as a neutral point, a point from which all distances are measured, it is appropriate to use Zero as this point. Zero is neither a positive integer nor a negative integer, hence it is perfect to represent a point of neutrality like the sea level.
2. The distance above the sea level is expressed in positive integers since they are higher in value than zero, and in the same way, distance below the sea level is expressed in negative integers since they are lesser in value to zero.
