: Sorry, but I forgot everything aboute absolute numbers over the summer. Please explain.

Given any real number n:
if n > 0, |n| = n
if n < 0, |n| = -n

As you already realized, a double negative is a positive, so in plain English this means that |n| is always positive.

For example, if n = 5, |n| = |5| = 5
if n = -5, |n| = |-5| = -(-5) = 5

OK?
