Absolute Value of a Rational Number Absolute value means how far the number is from 0 We represent absolute value of π₯ as |π| So, we can write |β2|=2 |3|=3 |0|=0 |β201|=201 The absolute value of a rational number x is |x| And, it represents its distance from 0 on the number line. Thus, we can say that Absolute value is always non-negative That is |π|β₯π Letβs do another example We can see |β2|=|2|=2 |β4|=|4|=4 |0|=0
