Yep, stay awake when doing inequalities. They instantly turn into gibberish with the slightest oversight, because they're referencing sets of values, not single values. If you don't envision them this way as you work, looking for set intersections and unions, zipping through problems crashes them every time, and it's really hard to unravel the mistake just by inspection. They are definitely 'right the first time' problems.
