@MichaelHale It's one of the less interesting questions, but I think that one of my favourite WL "killer apps" is the tracking of units like in question 3.
Yeah, that was one of the reasons I wanted to do the test, was use some features that I don't normally use. The Ctrl+= input worked smoothly for all of the unit combinations. But that was my first time using the net access since the 12.1.1 upgrade I guess, so I had to sign in again otherwise it just gave a cryptic no internet access error, despite network test succeeding.
I wish we had more transparency into why like #13 needed so much guidance.
Cool. I was considering the same. I mean, it seems like if it can do it quickly with those little bits of redundant guidance that it should be able to do it quickly as first entered.
#22 had a smooth progression of attempts. First try Sum, then NSum, then just Total@Table
So I at least had a progression of more manual fallbacks to try that is relevant across a variety of problems.
I've definitely seen some comparison discussions about Maple with regards to solving integrals. I think Wolfram put in a pretty successful effort to catch up. Haven't seen a Maple run for these problems.
I think you are confusing the sum having 137 terms with the power of the 137th term being 137.
