comment Perfect numbers less than 10 000
I'm not sure in Maple, but in GAP they can be found using Filtered([1..9999],i->Sum(DivisorsInt(i))=2*i); which returns [ 6, 28, 496, 8128 ]. It's just brute force computation; nothing intelligent.

comment New hourly rate after a pay raise
Does one really get 3 dollars for answering this question? I find that hard to believe. But, if it were true, by crowdsourcing, we don't even need to know any maths to make money. We can just copy/paste the questions here, and copy/paste the answers back for profit. Nice!

comment How can I print decimals in hexadecimal in Maxima?
I wouldn't worry too much about it; the about page is crystal clear: the question is on-topic here. As with questions about applied mathematics and statistics, questions about computational mathematics receive a fair amount of bullying on this site. (I must say, I love the irony in how the "on hold as off topic" message links to the help center, which asserts that the question is "welcome".)

comment How can I print decimals in hexadecimal in Maxima?
(a) I think it's worth pointing out that GEdgar's comment contradicts the help page for this site; (b) this question is about using the software to do maths: converting a number into hexadecimal (what's not mathsy about that?).

comment Re-write $1 \cdot x$ to $x$.
A large chunk of Adriano's proof (and the Prover9 proof) amounts to showing that $(x^{-1})^{-1}=x$. If we can assume this: $$1x=(xx^{-1})x=x(x^{-1}x)=x(x^{-1}(x^{-1})^{-1})=x1=x.$$
