In the previous segment, we learnt about integers and the number line in detail. In this segment, we will learn about the Absolute value of a number.
What is Absolute value of a number?
- The absolute value of a number tells us its distance from zero on a number line.
- It is represented using vertical bars to the left and the right of the number.
- Since distance can never be negative, the absolute value is always positive.
For example, the absolute value of -3 is 3, as it is 3 units away from 0 which is represented by |−3| = 3 .
Similarly, the absolute value of 3 is written as |3| = 3
-6 -5 -4
-3 -2 –
0 1 2 3 4 5 6
Absolute value
Few more examples are as follows:
(?)|−5| = 5
(??)|12| = 12
(???)|−129| = 129
- The absolute value of 0 is 0, which is neither a positive nor a negative number.
- So, the absolute value is either zero or a positive number. Therefore, in conclusion, the absolute value of a number is always non-negative.
