13 + (-12) - (-5) =

First, let us simplify our brackets (remove parentheses). Negative and positive signs rules: + and - makes -.
\(13 - 12 + 5\)

Second, let's continue to add and subtract now. Let's start off with (13 - 12) which will give us 1. Our problem will look like: \(1 + 5\) . Easy, (1 + 5) equals 6.
