determine the absolute value
of an integer by finding its distance from zero.
What is
absolute value?
When we find the absolute
value of an integer we are finding its distance from zero.
To do this, simply count from the number to zero. So the absolute
value, or distance from zero, of +2 is 2. What is the absolute
value of -2? If you count from -2 to 0 you'll find that it is
also 2 units away from 0. So the absolute value of -2 is also
2.
We use the symbol | |
to show absolute value. So to show that we are finding the absolute
of -2, we write |-2|. For +2, we write |+2|.
