I don't understand how to evaluate 2.28 please help me anyone?
Ostrovityanka [42]
Well, since the first 2.28 is in between the two lines you must find is absolute value.
 Absolute value is how many places a number is away from 0.

So the absolute value of 2.28 is 2.28, its just its own number. 

If you were working with negative numbers though, for example -7, the absolute value would be 7 because it is 7 spaces away from 0.
