Since the - 13 has the absolute value signs next to it, the 13 becomes a positive, but there is a negative outside the absolute value, and the negative sign and the absolute value sign cancelled previously, so the expressions is now

The absolute value signs cancel out a negative only inside the signs, not outside, so the negative sign in the outside keeps.
