comment Is it possible for it to be impossible to get to work on time?
The question in its current form is too hand-wavy to merit any serious answers other then, with sufficient reformulation of the question, yes, getting to work can be modeled mathematically and depending on the model it may or may not be possible to prove arrival on time.

comment Does the interval notation $[a,b]$ imply that $a<b$?
Yes, $a\le b$ is assumed. Some authors may further assume $a<b$, though most theorems remain true also for intervals of the form $[a,a]$.

comment non-symmetric version of compact = totally bounded + complete
Thanks @MartinSleziak, I had seen this paper and in part precisely that sentence led to this question.

comment If $u$ is a unit, so is $-u$
Write down what it means that $u$ is a unit. Then write down what it means for $-u$ to be a unit. If you do that, you should very quickly find the proof. For future questions do try to show some minimal effort. This type of questions don't really belong on MSE.
