The absolute value function takes any term and transforms it to its non-negative form.

#abs(9) = 9#

Think about absolute value as how many units the number is away from 0!


Or another way that you could think about the absolute value of a number is how many units away it is from 0. If you think about it that way, you can always remember that the number of units it is from 0 will always have to be positive. Therefore, let's say if you took the absolute value of -9 (which can be written as #|-9|#) then it would be 9 also because it, too, is 9 units away from 0.

Just a food for thought
